Ok,
I believe I have those pistons & those are really low compression pistons.
Not really good for high boost supercharging or turbocharging ,the top ring land is too high up. Can easily see detonation on your top ring & expose it & cause failure.
Not sure if you want to super or turbocharge?
If not, I would definately look into gettng a small chamber 194 head,which would give you around 9.3-9.5to 1 IIRC.
Install some lump ports & zero deck your block.
Take a measurement now to see how far down the hole your pistons are before you take it apart.
Part of the reasons why the newr LS1's & LS2'S can run higher compression is because they all have a positive piston height of .003.-.005 above the deck surface.Pistons sticking above the top of the block.
If you are going above 5000 RPM, definately look into getting an aftermarket damper V-8 style.
