9.48:1 with the .050 the gasket.
I would use a .039 gasket to get the compression up , you can afford to with aluminum heads
If you already have those 2 head gaskets sizes then use the thinner

Ok .039 is what I have so I’ll slap that on. That should get me to the sweet spot? 10.1 or close?

Next time you can use summit racing compression calculator & you'll never need to ask again. It will get you very close.
There are other kinds like diamond c.c. but it requires much more information.

I tried it and I was missing something and wasn’t getting the numbers correctly. Is it possible for you to fill it out and screen shot the entered numbers so I can see the formula. Would be definitely appreciative.

Yep.
Anytime material is removed from pistons like for valve relief it adds volume so use +
Dome adds materials which subtract volume use -.
Have fun. I use the calculator a lot , for trying to come up with stroker combos and piston compression heights. Kinda cool to know
