I also had a set of unmolested "C" heads, but with the bigger 1.66 exh. vlv. and machined in spring cups. The heads had one vlv. job in their life so it looked, as they still had Fomoco script valves in them. After I had all 16 seats replaced and the heads cut .030" the chambers measured out around 65-66cc's. Thats a far cry from what Fomoco published. I think the specs that Fomoco published were NHRA oriented. Travis?? JMO, S.D.P |
