Default What Compression?

I've got to replace my shortblock because the rod bearings bit the dust. While its torn down I'm going to send the heads in to get them trued up. I am running a TSP Torquer V2 232/234 600 lift ground on a 112. What would be my best compression ratio for this combo. The new shortblock will have -2cc valve relief and I always run 93 octane Ammaco fuel.

The higher the better generally speaking. Run a .040 gasket and mill the heads down a bit. You have room to play with since you have .100 relief in the pistons. Play with the DCR calculator to come up with specific numbers.

there is no clear answer to best scr since there are alot of variables but i'd say scr in the 11:5 range would be close.

Shoot for 11-11.5:1 and get as tight of quench as you can through a thinner gasket and milling the heads. More compression always helps power everywhere and driveability. The main limiting factor in your case will be octane.

Milling heads does not change quench at all.

I have 11.0 and my buddy has 11.3 and both motors run just fine on 93. Id suggest going at least low to mid 11 and use a .040 gasket for a nice tight quench as suggested. My buddy has this combo and its a monster.
