Pretty sure all NAs are the same and all SCs are the same but NA and SC are different from each other because of piston oiling jets.

I had heard maybe a head stud size change but other than that I don't know if there are any different or not I just want to build a motor with all forged internals so

Yes there are 10mm and 11mm thread head bolts. The bolt shanks are the same size just the threaded portion is different.
