Trying some new valves

[MOPAROFFICIAL]

I've run different brands and levels of valves over the years in different cid's and apps/power levels.
I've had good and bad experiences with some well known brands. When it comes to endurance with ragged edge compression and some of the more popular brands exhaust valves have not held up.
Anyways, I'm gonna use these valves in my full ported j heads that were on my stroker.
When I tore the thing apart I found that one intake valve head bent over at the cup from chomping down on bits of the Piston with 500 lb of spring pressure behind it and also that almost all the exhaust valves went oval. Plugs looked bitchin and as did the piston tops and chambers... just high spikes from repeated wot. I drive my stuff pretty hard and should have stepped up long ago in the valve department. I ran ferrea 5000 exhaust valves, never again...not unless it's a 9.1 stockish build.
Imo an elgin is better than a Ferrea 5000... 6000, not worth the cost the name, good but over priced ...
Anyhow I'm going with these

Engine Pro Nitro Black 10-3001.100-8...oh and imagine this, they're made in the same place as ferrea- Argentina. I got these for 108.00 plus tax in 2 days from my local engine parts supplier in el cajon. This is a tip I'm passing on to all of you...cause you can buy all the expensive aftermarket heads you want... but if you have **** parts in them, like what they come with... it's gonna be a 'do over' , you count on that.

So, what experience or feedback makes you think these are better than other options and these aren't made from hardened Argentinian cheese?

Chinese valves are what's in most after market heads. No brainer I'd think.
Thats 'Nitrided' argentinian cheese, lets get that straight...that's the point.
The ferrea arent nitrided, special alloy sure..for $$$
Go to the track and talk to the roundy round guys, methenal n alky people. That's what many are running. If you look in the catalogs... many entry level valves are decent, for the street...but we are building these things beyond what 'street' was ... in the pursuit of power..we are pushing the envelope more than ever....and gasoline IS NOT keeping up.

1. So, what experience or feedback makes you think these are better than other options and these aren't made from hardened Argentinian cheese?

What makes you think they arent?
"Maybe a better question... is are you okay with NOT being a mo'tor..?"
Let me ask you.. what heads and valves are you using?

Once you go black.......

You dirty ol man! lmao

My brother has a set in an LS,they've held up well to high rpms and heavy shots of nitrous. Hes going away from nitrous and going turbo and thinks they'll hold up for a while more.

You said I'm using these valves, they are the **** and provided no supporting evidence other than saying Ferrea valves either suck or are overpriced. Generally a statement of greatness is supported by evidence or experience. You provided neither. Thus the question. What I am using now or may use in the future is of no consequence.

Argentinian cheese...mmm mmm...

They are highly recommended, as I said.
You can read after that, if you really wanted to learn anything you could go to their site.
Less prone to bend, break, crack, wear, build up from fuel gunk etc... read the site.
You have no proof otherwise.
I asked you what makes you believe they arent... and nothing...because you dont like them? Because you're too lazy to search? Because you've never heard your guru machinist mention them? You buy stock in ferrea? Lmao
Knot head... u come on my thread completely rude, biased n debbie downer on a product you yourself admit you know nothing about.
Pfft, well...

That word has a double meaning in the industry...the "environment"...means the 'operational "environment" inside the engine' ;)

not a bad price for imported cheese.

Thats what I think. Everywhere else was 140.00 a set of 8.
They make a 1000, 2000, 3000 series valves. I've used the 2000 series intake valves with no issues. That was the one that bit down on piston rocks and bent the lip over a little. Hard seat held up. Bent but not broke. They improve the flow a couple over some others..but if those others just finished them themselves they would pick up as well. Finish is where is a lot of it is once you get into higher end valves...then under head angle for a particular head...but in general, quality.

Do you have any experience with Milodon valves?

 

[MOPAROFFICIAL]

Do you have any experience with Milodon valves?

Yes, they are a good valve.
A lot of valves are 'good' it's when you get into proprietary alloy the game is another level.
Most 1 pc. Stainless 11/32 2.02 undercut valves weigh around 124 grams,except ferrea 6000...125.6 grams. Meanwhile a EP 2000 @124 grams ...and milodons way lighter still
Milodons arent most valves in that regard, some are very light for a steel valve...now I've never dropped one to find out how brittle they are or not.
Competition friendly, yes, how long...? Idk

Just curious... what makes the exhaust valves 'go oval'? Just guide wear? Have you been using roller tipped rockers?

You brought the topic up and provided no supporting details. I don't see why I should be required to go research why they may or may not be. That's usually info that comes with a recommendation. I'm sure I could go on Milodon, Ferrea, Speedmaster, or Promax's site and get all kinds of guarantees that their stuff is awesome. Not going to convince me to buy them though let alone from a company I have never heard of. Was just looking for the info why you would go out of your way to bring it up. If you take offense to that, I can't help you.

What is the length an diameter?

You got a part number for these cheese curds?

Ihave many hard miles on my Chinese I suppose valves on my stock eddy heads and whatever Hughes put in my bigmouth heads and have yet to have a problem . Your valves might be the best ever , but advertising copy is just that , i'll look up info on these valves for sure it's just i've never had a valve problem , the price is right if I ever need valves I'll check these out , thanks for bringing them up , never heard of them

Thread is called 'trying some new valves'
Now what?
No one is twisting your arm to go out and buy them. It's turning people on to some valve tech..something reasonably priced.
You're just here to stir it up.
You don't like my opinion? Tough ****, don't keep coming back.
Id ask , again, what do you run for valves, but I dont care anymore. Your rebuttal is empty..you are right at the edge of arguing punctuation next...so yeah I'm sure you're in no way trying to be offensive... because I hoemstly believe you were born an asswipe.
Ignore list, along w/jpar and many other 'fabtastic friends', without even noticing... because like them..
..you don't offer anything other than a headache or an X.

From 1st to last quote in bold.
Isn't it scary how some people don't even know what's in their engine? Isn't it scary that guys get into wanting high power engines but for the most part have no understanding of the mechanics and seemingly have no desire to.
The big mouth heads, if you have them re tested, may have you trowing them through Dave Hughes shop front window.
Search member @Ironmike and look for his thread on them...also bloomer heads.
With that said... "have yet to have a problem"... you and me both have no idea what cam is in your engine and I personally have no idea how often and how hard you drive your car and I do not know the overall combination or compression. Fwiw Even a stock valve can handle whips to 7k, and your average flat tappet cam build...the Chinese is a step up. It's how wide that margin is though before you need a better valve...and that bridge to the next level is short if you are looking for regular service life and not a season car.
"Its just that I've never had a problem"
Hopefully you never do. I'm on your side..trust me.
But if and when you do...you'll get it.lol remember this thread.

I'm a solid roller guy turning 7k with 410 cid and cranking 184 , quench dome pistons, .030 quench distance...iron heads heavily ported by me and flowed on my own bench, motor built by me. Heads assembled by me, set up...everything... picked my own parts. It's what I do as a side living. Just a little insight I to the usage of the parts in question. Maybe someone should have asked ,right?

"Never heard of them"
I think that's the real issue for some...
Racers and builders know. Joe schmoe..not so much.

Just curious... what makes the exhaust valves 'go oval'? Just guide wear? Have you been using roller tipped rockers?

Ca pump 91 vs 184 cranking vs 7200 vs elevation.
Have the tune good...but I'm at the ocean...elevation changs abruptly upwards of a 1000 ft... I go from 564 to sea level in 8 blocks. This is the reality of ragged edge...
You will always be ******* with it or enduring momentary lean spots up in the r's. I can drive down the freeway in 80 degree weather.... then 10 min south on the 5 hit a big marineayer or cold front of 50 degree air.
I need exhaust valves that can handle a rainy day. Once they go oval...and it can happen in a blink... its heads off time.
I'm one of those... trying to make the most durable, versatile, well rounded pump gas monster I can muster.

To you question...roller rockers, center sweep..still not perfect though. Getting a geometry kit soon from Mike.

Thanks for the heads up on the Milodons. My friend with the 340 got a smoking hot deal on a set of X heads with a set new set of Milodon valves, banana grove shafts, fresh springs and factory iron adjustable rockers, to boot. Just wanting to make sure that part isn’t too good to be true. Being he got the whole deal for not much more than the cost of support hardware, I’ll be checking the heads out closely.
