edelbrock cylinder heads
Intake ~175-180 Advertised at 179 IIRC
Exh 67-68
Chambers are anywhere from 62-68 or so from what has been observed. Nice thing with Brian, he'll cut them to whatever you want.
The talks I've had with a few people, we seem to think the RHS heads would work really well on smaller CI mills for a few reasons. I mean these things with the 2.02 and nothing but blending the bowl cut, make 500hp on 400 CI engines which isn't shabby with no porting. You can't get that out of some of the other heads which I won't mention. LOL
My opinion is, for the money, you can't beat the performance of the RHS head that Brian does, PERIOD! For what it would cost additional to get the alum head to that level, porting, springs, VJ and surface, you could buy roller cam gear and RHS's.
Make your choice, spend you money.
Patiently waiting for the normal pissing match to start. :-D
