forged 10.5:1 compression piston options

[asusual]

Hey guys! looking out for a forged piston thats close to stock compression on an s52.

Im aware you can order some custom options from JE / Mahle but dont have the time.

Found a set from wiseco that seems promising but cant seem to get the calculation right? Does anyone know the compression on these?

I've used Ross with good luck before-
hardly any more noise than stock, good durability.

Given that you're looking for parts for a 35 year old engine, the time to make
these isn't bad compared to the (non) availability of anything 'on the shelf'
I think Ross took a week or so, back when.
