How many times can rod and main bolts be torqued?

Well - the rules have always said no porting in Stock. But that didn't stop many from doing it, acid treating the ports, and then trimming the manifold flanges to give back the volume increase. Ther are no go-no-go gages for factory ports. His Super Stock engine (runs mid-low 9s in a later model Mustang) is drastically different from the shortblock up from the stocker & part of his invetment to go up to SS was his own SF-600 flow bench. The heads are radically different. I've never met a more methondical and detailed guy.
