Default RE: Lapping valves on OS Surpass
I HAVE BEEN DOING MECHANIC WORK FOR OVER 45 YEARS. I DON'T SEE ANY PROBLEM WITH LAPPING THE VALVES IN THIS HEAD. WHEN YOU LAP VALVES YOUR NOT ACTUALLY TAKING VERY MUCH MATERIAL OFF THE VALVES OR THE SEATS. THERE SHOULDN'T BE ANY PROBLEMS LAPPING THESE VALVES AT ALL.
