If you were to compare all of the current big block heads( not including B1, Predator), who has the best combustion chamber design?

Take into consideration that the typical street/ strip car would use these heads on a daily basis.

I have always wondered this and I am not knowledgeable enough on heads to form an opinion.

Thanks!

I am partial to the Indy stuff, based on the wide spread you can use the various heads on. Anything from a 361 to a 604. Small ports, bigger ports, stock placement exhaust port versions for A bodys, combustion chambers can be sized to work with a variety of engine sizes for pump gas and flat or dished pistons.

Strictly combustion chamber? B-1BS. S/F....Ken M

I would think it would be the head with the highest
volumetric efficiency .... I'm not a BB guy so I
cant really say which is better

I think most of them are decent, it's way easier to say which are worst; RPM and 440 source. But Indys and Victors both have pretty nice chambers, haven't used BS's so really can't say. But I guess they are good too, although small.

When you think about it, there is a reason to pick any of the heads mentioned, depending on what your intended build is. I believe the B1bs heads have the smallest as cast chambers? The RPMs are a good standard port head, the Stealths are for a tight budget, an the Victors kind of fill a gap between the SRs and 440-1? So if you are thinking of a certain motor combo, guys could be more specific.

I didn't have a certain motor combination in mind, I was just thinking about modern style heads for the big block.

Okay, how about this: if someone had a nice 440, stock stroke and went from 84cc rpm heads to victor heads ( both standard opening), what could you expect?

chrysler 426 street hemi cylinder head is the best.

Look at the latest NASCAR combustion chambers, they would be state-of-the-art for a two-valve design. Then find the head that most closely replicates those. IMHO they pretty much all look the same, between the four engines.

All current out of the box chambers offered for the wedge MOPAR, except the Predator and custom PSO stuff are outdated and inefficient.

There are no exceptions, as ALL manufacturers of these heads.....Indy and Edelbrock included, obviously doesn't care about modernizing their designs for the MOPAR crowd.

I hear ya and agree and plan on someday replacing my e-brock rpm junk w/some good heads and intake THEN this puppy will fly..........

Some of the suggested heads and chambers would be GREAT but just remember some of these come at a cost, RPM. And RPM costs lots of MONEY. And lots of Mopar racers have MONEY but don't like to spend MONEY.

Poly head....

The OP said big block and eliminated all the serious race stuff. He also just asked about combustion chambers, which is sort of odd, when there's other things much more pertinent to making power. The BS comes in about 65cc and when CNC'd about 75, which is about where you want to be with a flat top piston.

AFAIK, none of the common Mopar heads come with semi finished chambers so they can be properly CNC machined, as is SOP with serious stuff, but the BS is probably best suited to this, for the reasons I mentioned.

Would that be what I recommend? No, I have a set of Victors for the engine that's going to the step down from the B-1. That would be my suggestion at present. S/F....Ken M
