Most aftermarket blocks even Chevy etc there is going to be some work involved. Casting flashing to remove(check cam tunnels) possibly coolant holes to drill. Mike cam bearing holes too.

Wow, I was not aware they could be that far off... thank you for the helpful and very useful information!!!
The machine shop had to order a tool that fits his machine in order to measure / deck the Pontiac blocks. Once he has that he will be checking the decks to insure they are both the same heights and correcting any discrepancies if found.
