As I recall the 1967 375 HP engines had 2.08 and 1.75 Valves and were stamped HP on flat area on front of head. The lower HP versions such as in the full size none HP "C" body had 2.08 and 1.60 valves. Only apparent difference was valve size...casting was identical on all 915's. You do have to run original stock size exhaust valve on early engine 1.60......but they still work fine. John Irving
