Hey thanks for the quick reply!

I used a wallace racing calculator that had an input for intake valve closing degree and altitude.

They are step dish pistons w/ valve reliefs, 19.4 cc head volume
They're defiantly zero decked
I only guessed on the head cc. Stock is roughly 72cc and they were shaved an unknown amount.

Compression numbers look level so I guess I'm good to go for closed chamber heads?

A set of RHS heads with 62cc chambers brings the compression up to a true 9.3:1

I'm about to drop 4k into this truck as soon I get back from deployment with goodies like RHS heads w/ roller rockers, headers and exhaust, air gap intake, demon carb, and 4.10 gears.

How much ignition advance we talking about? I was thinking roughly 32-5* total.
