Pop can, beer can, piece of steel roofing , what does it matter if it works. My question as I have never heard of machining the bell housing to be parallel with the block, which surface gets re-surfaced ? the block side or the transmission side. I think a person can micro a project to death trying to get something perfect when there is tolerance that is acceptable .
it's ok to butt heads, just don't do it with a butthead
