As I recall, when I did the head on mine, I checked the compression after it was done and I was getting between 168-172 PSI. But, this was after shaving 12 thousandths off the head to level it out. I think that factory should be around 160-165 PSI. My engine had 165k on it when the head gasket blew. As Donnie reassured me, the bottom of the 103 engine is pretty sturdy. Guess so..
