318 LA rebuild after losing a valve seat

I'm going to get some final numbers after I've got the degree wheel installed, but some rough measurements I got were ~3.380 @ BDC and .085 @ TDC. Bore was exactly 3.950. I did notice some differences of about .005 depending on where I was on the piston when measuring depth. Is that normal? They are just flat top pistons with no reliefs cut.
