Out of hole calculations? If I'm running a factory 3.622 crank, factory un-milled LS1 block is there a way to calculate with piston specs and rod length how far out of the hole the pistons will stick out?

I haven't purchased pistons yet. I've had a bolt on car and a head/cam car, both with stock shortblocks. Now I'm doing a h/c car that a spun a bearing on and I'm redoing the entire engine, both bottom end and the heads/cam setup.
I've looked into Mahles, Diamonds, and Wisecos. I like the look of the Diamonds the most because they carry the least amount of relief and the appear to be the lightest at around 410 grams. But I just noticed all of these have a different compression height
Diamond: 1.315
Mahle: 1.34
Wiseco: 1.304
Will this affect how far out of the hole one will come compared to the next? If not what are the pros/cons to higher/lower compression heights. I'd like to have my ducks in a row BEFORE spending $2,000 on a bottom end
