no compression at moment- prob end up with 8 - 8.5 - prob gonna run 2 head gaskets 2 keep it down - it's in pieces once again - waiting for parts - minimum of a month delay to get stuff to nz from the states waiting on forged pistons and rods - but am having second thoughts as to whether theblock is gonna hang in - debating buying a new block - probably won't till it cracks - cam is a crower item 15929 Turbomaster - also waiting for it to arrive - am in the process of fabing upsome new exhaust manifolds - estimating an easy 500 ponies at the crank

oh yeah that's what i'm talking about.ever since I got this clevor manifold from a swap meet I've been wanting to build a 302 with the heads and seeing as to how I've been putting this twin turbo together I figured what the hell.
good to hear someone else is doing it.I really won't be seeing high rpm with this motor in my 4x4.that's why I was wondering about the heads.
good luck on the project and I hope it meets you expectations.

Just MPO but the 2b heads could restrict total flow. You could also work the heads to help flow and increase combustion chamber volume too but I would never use more than one head gasket. Just too many ways to blow it out with boost. Since your using a twin setup total air volume can be huge with relativley low pressure and hence the need to ensure a good seal.
If I can find the spec card I'll post the spces. We used an Isky cam on a 302 with great results
Good luck with this project and let us know when its "alive".
