I would just simply suggest that you tell the machine shop what headgasket that you are going with. This is to insure they put the proper RA value on the head deck so the gasket will seal properly. Cometic recommends less than 50.
The slight bump in compression from the massive 7.8:1 factory compression ratio shouldn't nuke your motor. I would be more concerned as to why you blew a headgasket in the first place.
