I used pre-cut rings the first time and failed to check end gap. Also used a new machine shop to keep my rivals from knowing we were pulling an engine swap. Went from a 327 to this new motor. So to answer your questions,

 No the block is not cemented at all.
 The last 3 numbers are 511.
 By burned piston I mean that they have they both have an edge of the piston burned off making the top ring visible.
 And what do you mean by 4 corner cooling. The intake we’re using is blanked in the rear. No crossover ports for the rear of the heads.
 How do I achieve 4 corner cooling.

We will be going back with file fit rings this time. I rocked the pistons from side to side and the bore seems a little loose.
What should the actual bore be for .030 over slugs?
Any help would be appreciated.
Constructive criticism welcomed.
