It's really a decent quality street head that is readily available and can be bought off the shelf from several vendors economically at different stages of porting to support anywhere from 700 plus bracket builds to 1000 hp aftermarket block builds.
I believe it's won more races than any other head produced for a Pontiac. Also it's the only legal NHRA aftermarket Pontiac head.
There is an emissions legal version available for states that require it.

Paul although it has displayed a great deal of accomplishments, that doesn't technically describe why it's a great race head.

So a lot of people are saying it isn't a great race head. But are we talking about a bracket car or a heads up race car? Because I think it might be a great head for someone bracket racing or running a 10.90 class .

Pontiac Racers have always been handicapped with poor heads. That's what's cool about an Ehead. You can drag a Brodix headed BBC down the track with a Performer RPM street head.

... very good points, most are true IMO, i'd like to see them on the dyno making 3g's, maybe i'm wrong, but i do know what it takes to make that kinda power, i'd be very impressed to say the least ...

... the other part is to my knowledge there's only one engine that has made or exceeded 1000hp N/A and that's Leech and Co. so i wouldn't look at that as an automatic thing, those guys have done a great job with a big pair of hand cuffs on, but impressive to say the least, at this level one of the key limitation gets in the way, which is CSA, but they've done a great job working around it, but just not the norm for any other EHeaded combo certainly, i'd say for Pontiac engines the list of poeple that have made 1000hp or better is fairly short ...

... what i'd personally like to see is a set ov my CV-370/Raceplate heads on Leech's engine with one of Marcella's bad boy manifolds on top, now that would be very interesting IMO ...

... there are Brodix headed BBC's out there that make over 1400hp N/A in crate form ...

... but certainly not all ...

I agree that would be interesting. Do you have "off the clock" access to a dyno at Sonny's?

Based on it's performance, a set of eheads ported by Tom Slawko made over 1K hp on a 525 engine. It is currently owned by Karl Owens (KO) on here and is for sale in the parts forum. BTW that engine was built in 2009.

Race the one's that don't ...they're usually polished.

One mite ask what is the definition of a "GREAT RACE HEAD".
Did that not start in late 1954?

Big Chief just said on FB his new Butler block combo will use his E-heads.

Thanks for the info.

EHTTFMF's!

The e-head broke open the market for aftermarket Pontiac heads. People were finally able to lust for something other than collectors item RA4's. It's since been eclipsed by newer designs but you can never take away its contribution to the hobby.

Same comments about the Indian Adventures IA-1 blocks.

Another nice feature is they are available without pushrod holes so you can easily put them where you want.
If you know the right people they can be had without the guides and seats installed.

I agree, the ability to increase CSA by getting the push rod out of the way is a great benefit.

X2, great upgrade path from the factory iron without changing much.

Good question, the Hemi was designed 1951 I think. The 127/980 great heads for racing at the time.

The RAIV and SD heads also great at the time.

Eheads are easy to make look like a factory head.
