anyone use these heads on a 360 magnum engine? just wondering how well they work. I have the 360/380 hp crate engine and saw these with a stage 1 port job, just wondering if I would benefit if I bought and installed these over the heads that came on the crate engine
 
Yep. Bigger port sizes (stock intake port 153 cc's,E/Q intake 170 cc's) tighter cc chamber size( stock 62-64 cc,E/Q advertised @ 58 cc's ,airflow @ .500 Stock 210-215 cfm/EQ 230-235 cfm. (1.92/162 stock valve sizes) LX guy( member here ) got a 70's Dart to run 11:70's@ 116,basic stock EQ heads. Check out Magnumswap.com,for more info on his combo. If you want a bolt on set with bigger valves & better airflow potential, contact MRL/ 0u812( Brian-IMM engines)/RAMM/or IQ52 here. All have extensive experience with these heads.
 
These heads seem to have a pretty good rep but I'm not sure that they have a real substantial advantage over mag heads unless you get them ported. Either MRL or IMM should be able to fix you up.
 
I assume your heads are low mileage. Why not port what you have. I have a 300 HP crate and a mild port and bowl cleanup made a big difference.
 
We're getting ready to build a budget 5.9 magnum with EQ heads, 9.8:1, hyd. roller cam and 4 BBL intake to see if we can get more than the budget 350 chevy we did...should be close!

Saw you got the Car Craft gig,Brian. I enjoyed your 340 stroker, & the low buck 350 build. Impressive numbers on that HT383 hyd roller grind. Stoked to see a Magnum build ,again.
 
How do they compare to the aluminum Edelbrock offerings?

My needs to lose weight so I don't have to.
 
With minor porting the edelbrock magnum heads are very good! Actually, they are better than the LA heads OOTB for power as well...the LA will flow more air (more potential HP) when all out effort porting is done, but for street/strip builds I like the magnums best!
Brian
 
flow bench says EQ has a bit better flow OOTB although most edelbrock lovers will argue that point. Seat of the pants dyno, I think the EQ feel stronger but that might be me. If you bolt on a set of EQ heads you should see 400+ hp from that short block/cam combo.

check out this article....http://www.hotrod.com/how-to/engine/1503-59l-magnum-engine-make-mine-a-5-9/

Pretty straight forward as far as engine builds go and a good base line to start with to decide if you need more than 400 hp.

With bare sets under $800 shipped and complete w/larger springs for that cam at under $1150 shipped, they are a pretty good deal. All our customers that have them have absolutely loved them.

Brian, what's your thoughts on the EQ head or the Edelbrocks hp potential? Fully ported of course.

Fully ported the Edelbrock will make at least 30-40HP more than fully ported Indy iron or EQ heads...then you go Indy's for another 30-70Hp more and so on....
Brian
 
Not so impressed by that build considering the create engine as developed was labeled a 360/380 engine that consistently delivered 400+ HP with a smaller carb.

Looking foward to your build Brian.
 
Just got this going this fall with ironside (Andre) here on the board here in Kalamazoo. 5.9 Mag out of a Ram for $300. Rebuilt it stock bore block and stock rotating assembly. Hughes roller, and Iron Ram heads. Re-used my LA Eddy air-gap and 750dp. Runs really really strong. No dyno tests but hoping to get it on the chassis dyno in spring here in town. Used thinner head gasket to bump comp up from stock 9:1 to 9.5'ish - 1 range. Love the Iron Ram heads for the $$. My stock Mag heads were beat. Basically followed the LXGuy recipe more or less and Magnumswap.com info.

Brian I'll be really interested to compare with what you build!

Thanks Brian.
 
If you check out this months car craft we did a 350 vortec chevy engine that made 435HP using stock bottom end vortec, EQ heads, air gap style intake, hyd. roller cam, etc...now...without letting too much out...we are building an identical 360 mopar magnum built to the exact specs of the vortec...9.8:1, EQ heads, even the same brand of headers keeping everything comparable.
I expect both engines to be almost identical in power delivery in graph form. We'll know in a couple of weeks!

Thanks for the heads up,Brian. Really enjoyed the 350 (2nd stage)/ And that 302 Explorer/B303 build. Didn't know, Trick Flow offered a high lift valve train option.

My LA 360 has the Magnum EQ heads on them and so far they've been great.

I have only been scooting around town so far since I'm still in the middle of the build, but drivability has been pretty good on the street. I haven't hit the highway yet.

As far as power goes, with the combination I have (cam, etc.) it made 403 HP on the dyno and gobs of torque. I'm really liking the torque!!! By the way, Brian built it. Thanks Brian!

So, if you do plan to get EQ heads then get them from Brian (IMM aka ou812)!

I have that issue right here! I'm not a Chevy fan, but I do admit that I was impressed with that build. I really like what you did with the Ford too.
 
They flow better than the stock factory head. I don't think that you will notice it. There is a drawback to the head if you try to go larger than a 1.92 valve. There just don't flow well into the combustion. I did this and although the flow #'s looked good the combustion efficiency went down. A MP factory pocket ported 596/2.02 head flows better and makes more power. I Super Stock ported a set of EQ heads with the 1.92 and they are impressive. You are talking about 5K of porting work.

where did you get this info? if it was personal experience, do you have flow # or dyno runs to prove it. What your saying is backwards from everything I know about all these heads.

So what are the numbers? I am trying to do this exact build right now and am waiting anxiously LOL.

445HP and 450TQ!

And that is with the magnum? That is pretty damn impressive. What kind of cam did you go with? I'm guessing a custom grind but wasn't sure of the duration. Carb use etc.

Shelf Comp hyd. roller, 230-236@ .050 on 110lca. Carb was box stock 750DP. OOTB EQ heads prepped by us, OOTB airgap intake, 1" spacer and TTI headers.
