318 with 675/318 or 974/360 heads Cam Recommendations

.070 down the hole is a bummer. It's worth it to try and find some Pistons to get that up to the deck.

The worst thing you can do is kill compression and then put a cam to it.

I mean, you can deck .070 off the block but no way will you not have to mill the intake manifold to fit. Then the $$$$$ just start adding up. And that's way too much money to take .040 off the heads. In reality, with the piston that far down the hole, the .040 off the heads is like pissing in a river. You are better off just cleaning up the heads and decking the block.
