New engine pics!!!
I was worried about that too!! They are the 340 heads that are machined for the above-deck pistons. I'm going to do some slight unshrouding in the chamber also, since my bore is 4.1, so hopefully that will help the hp and lower my compression too. I think I can get it down to 11 or so. Heck, gas is so expensive, I'll even mess with the timing if I have to! The guy that had my shortblock ran edelbrocks and indys on it, and he said he ran pump gas with no problem. But, his cam was in the 270@.050 range, I'm sure that bled off a little pressure. I hope I don't have to run race gas.
Airwoofer, what compression are you running? The pistons are JE flattops.
