So just got done with more work on the block,
Checked how much my pistons are out of the hole(Had concerns at first but figured out i wss reading dial wrong D'oh!)

Left bank varies from .003-.005 out
Right bank varies from 004-.005 out
Happy with results as if my calculations are correct this motor with the head gaskets i plan on running with be 10.5 to 1

Degreed cam
Oil pump and pickup
Timing cover and water pump
Oil pan

I will post pictures in morning

That .002 variance is most likely stroke length indexing (meaning not all the throws were ground exactly the same and this is quite common) connecting rod center to center variance, pin height differences or the tolerance stack up of some or all of those things.
