are you aware how expensive aftermarket heads are? If i had the money i would get some kind of GTX heads or whatever the aluminum ones are called... or something else.. AFR? i forget who makes the low comp heads.. and i would use some custom pistons while i was at it.
Anyone know of any companies that sponsor hot rods? /forums/images/icons/smile.gif
1. Aussie heads are CLOSED chambered with 2V ports.
2. Cleveland exhaust ports are labeled restrictive because they don't flow quite the ridiculous numbers the intakes do.
3. Even 2V cleveland heads with almost no work flow as well as most aftermarket windsor heads!!
Yes, the exhaust ports are very "kinked". In the 70's, racers like glidden sliced the exhaust port outer half off, raised it a bit, and blended everything together (and from what I've read, glidden ended up with a cleveland that "revved like a dentist's drill")
Shagg, the open chamber heads were 76cc....flattops create about 9:1.....dished pistons would probably be what was required for forced induction, and theyd probably be custom for a 302. /forums/images/icons/smile.gif
