I hope I don't sound like I am beating a dead horse, but I really want to be sure I'm going the right way AL vs. iron heads. Right now I am building a 95% street 466, going into my 71 Mach 1. The shortblock is an early 70 block, so it should have the shortest deck height. I have the TRW dish pistons (2404s) and in an earlier post the consensus seemed to be that it would not be worth swapping these out for flat-tops. So I am thinking I would be around 9:1-9.5:1 with small CC heads.
I like the idea of AL heads because of the weight issue, but lately I have been reading posts here (actually on the old board, this one looks great by the way) that make me think that if I use AL heads then I would need more compression than the 9ish:1 I would have.
Right now I have some DOVE-Cs basically fresh w/ no port work whatsoever. I have talked to a couple of people here about some ported DOVEs and some Edelbrock RPM CJs they have for sale, plus there is the option of buying some heads new.
I'm hoping for a decent 475-500hp at the flywheel by the way, and I would like to be able to run 93 octane. So--what would you do in my situation heads wise? Should I start looking at changing to flat-tops again? I want to do this thing right the 1st time.
