Thanks. If the valves are bent (I don't think they are). I'll have the front side dressed a bit. I don't think they are bent(will pour alcohol in runner to make sure).
I'm running a dual cam motor. The intake cam is a couple of degrees advanced. the exhaust is straight up.
Thats what it liked on the dyno.
If the valves are good I'm just going to throw the thicker head gasket in and race it. I can't run a bigger cam till I design a new piston. (Over the winter)
