Default Whats my compression ratio with these AFR 225s?

It's an LME 408ci, eagle 6.125 rods, Wiseco -8cc pistons. Stock GM MLS head gaskets with AFR's small bore 225's milled .018". LME advised me piston was .010" out of the hole...... Whatever that is

Assuming use of a 4.125 bore head gasket with a compressed thickness of .052, scr is approx. 11.35:1
