TrickFlow heads. A few teaser pictures

-
Ok guys I’m sorry but this had to be done. I made a 80 mile trip for my shelving parts and stopped on the way home to take a 1.6 mile RiverWalk. Then I tore out my cheapie shelf and cleaned up the one I got from my buddy. Put it in my shop and got 15 heads that were standing on end in my shop properly stored and out of my way. Even have room for more so I’ll probably put Matt’s Edelbrock heads on it. I’ll leave my extra set of B1 heads and two sets of 440-1 heads in the shop. One more TrickFlow head is on my porting bench and one Edelbrock head on my valve seat machine.

you need a few more intakes to top all of them heads.
Their probably hidden somewhere else, right ?
The shelves are nice.
 
It was not a scientific same day back to back swap…but it was enough for me to be convinced W2s make power beyond what the flow numbers suggest
 
I'm going to watch you two Godzillas duke it out. Much respect sent to both of you from an old man. Drive on, Brothers.

ONLY if the engine is accessing it! Most likely it's due to some flow, Pinch, ex. port, different intake?

This is half the mystery to me in the way people will purchase heads, brag about them, how much they flow before and after porting, make claims of huge power gains, but yet never change the broom stick cam, add a rocker ratio much less anything else. There lifting the valve around the .500 area but can’t stop talking about the big flow numbers they never reach.

Well that’s 60 horsepower in flow alone if it was in the usable range. And I’m betting the low cfm numbers were better too so it’s a win, win, win.

That’s why I worded my post like I did. “Useable range”. If I gain 30 cfm within the limits of my cams lift range I will see 60 horsepower gains. Especially if it’s in the .300-.550 because I’m using that area more than I am .650.

I built Billy's engine using those heads...I spec'd the cam, he wanted 11:1 compression, it made 605HP on my dyno. And yes I went over the heads very well...they made HP even though the flow numbers were not as advertised.
I also did a set of Eddy heads for a customer in a class, to replace his AW heads that started to have the spring seats sag...I told him he'll probably run within a .10 of the AW heads. He PICKED up a .10 and 1 mph with my heads! Flow numbers should not be the reason you buy a certain head. Can't say that enough!!

When Larry did my heads the shipping and payment went through Todd Marsh (a great guy too) because Larry wasn't set up for it at the time. Todd called me and told me they were ready to ship, he also told me that the flow numbers weren't very impressive, but not to get hung up on the numbers, that the heads would make good power. Compared to what I'd seen other head guys post for Indy heads I was disappointed when I saw the numbers, but I trust Todd, and Larry's work, I haven't been disappointed.

Important lesson learned, there is more to heads than just flow numbers.

Yes there is. Flow numbers are pretty low on what’s important when looking at cylinder heads. Shape, shape and shape. And then a properly sized port. The valve job is far more critical than flow numbers.

I’m not saying don’t look at flow numbers. Just don’t base your thoughts on how good or bad a head is by flow numbers.

excellent post!
 
Ok finally got this head on my flowbench last night. Left column is stock on my bench and right column is after welding head up and opening up the pinch .100. After church I’ll post up numbers after a little more work. This is still with the stock 2.02 valve.

Was it worth the work? For the average Joe, better to bolt them on out of the box?

That is a pretty significant increase. The cfm deltas double from .300 to .500. +3, +6, +12. All in a usable range.

Well done. Are you taking any porting orders? Lol

was it worth the work??? Heck no, but it’s hopefully a stepping stone to make it all worthwhile. I would advertise anyone working on these heads to stay away from the pushrod side of this head as TrickFlow took the safe amount away. More later

I just want to say, that I take great comfort in knowing that you and many other guys of your caliber and reputation and knowledge are continually lurking on this sight and sharing your experiences. There are a multitude here that thrive on the information provided by those that have “been there done that”.
Threads like this are what make this site what it is! Thanks guys.

Great work, as usual, John. You, sir, are truly a pioneer. :thankyou:

Are you measuring air speed in the port, before and after? What I don't like about that head is how small the pinch area is compared to the short turn "area" and then the 2.02 valve. Kind of weird but if you run a large enough cam they'll make power.

I just do this everyday, so after a while you get to where it's just second nature...when I look back at how I did heads 10 years ago, yes I do things different but still reference off of what I used to do because things I did back then worked too. Thank you for the acknowledgement, but just know there are smarter guys out there than me! I have to work really hard for everything I find. But some say it builds character...LOL!
 
@ou812 And then people wonder why head porters don’t spill all of there secrets & they (the people asking the head porter) get all upset and angry. This knowledge is not easily gained by one’s self.

while numbers are nice. Until the heads go down a track, they mean little.
Have yet to see any trick flows that have produced good track numbers, compared to other options

Hey John, if you haven’t changed it yet, can you give me the throat % for the intake and exhaust on that head?

Playing with PipeMax and I’m getting numbers that don’t make sense, and I think it’s related to those %’s.

TIA
