Has anyone used a 54mm DRATV high compression piston with a TB Race Head? I think the TB head may have a smaller dome or the TB300 cam is too big. Getting tons of top end noise that we didnt have till I tried the DRATV piston...........

Any thoughts? I was thinking about trying the DRATV 1.5mm copper head gasket for more clearance?

probably intake valve tapping the piston...pull the head and you should see where it is hitting......might have to grind abit more relief.......clay it up and you will know 4sho
