Ask one of these performance shops to split your block and check all the clearances etc and put it back together, then move on to the heads etc.

Yes it will suck paying for it twice but that should be enough piece of mind for them to move forward with the build.

Did the engine builder send you the clearance numbers with the block. I was told that is how I will receive my block when it gets here, sometime this millennium....

Who is the engine builder? PM me if you don't want to go public.
