Zero deck and steel shims? .017" quench? Sorry, but the pistons will hit the heads! .030" is the absolute minimum, with .035" indicated in most books.

I know there's a way to do this...

Have you thought about increasing displacement? A 428 crank or a Scat stroker deal might be just the thing for more compression.

Ross racing pistons makes some pistons that might help? Maybe too expensive though. Maybe come early C0AE heads with the ~60cc chambers, if you can find them?

I know Dove makes some small chamber heads. I'm sure they're pricey though. Might be worth a look.

Let me think about this for a while. I might come up with something.
