Well, maybe stock cr and the CNC heads can make the difference. 75hp is nothing to sneeze at, and heads are definitely where to find it. I respectfully remain skeptical.
I do agree about the exhaust. If I remember that cam has around 16* overlap at .050.

Now, just a little perspective here, that is one hell of alot of money for 75 hp.

Hey Bob,

Everythings going great on this side of the river. How 'bout you?
Yes, you will definitely see my "creation" on the water this year. I've got a machinist fabbing a bracket for me as we type. :D
