OK...static compression question

Here's the setup.... 350 standard bore 3.48 stroke inverted dome -24cc pistons and fast burn aluminum heads 62cc combustion chambers? What might be my static CR?

not looking for exact figures here but something to go on so i don't have to send 1500.00 on new heads and invest that money in a 5 speed.

All opinons welcome.

I think that might work for a while? I just have to figure boost ratio to keep it under 12% or at least 7 lbs boost.

Deck is standard ..as it is a GM crate motor with 7k miles on it. gasket can even go up to .051 i guess
