I'm sure the valve spring will be compatible as I have the Edelbrock Performer RPM heads and they are supposed to be compatible for up to 0.600 lift. The valve to piston clearance is one thing I'm not sure of. Maybe somebody else out there has done this combination and can enlighten us. GT-347 out of all of those cams that you have run, what one did you feel was the best. I assume the 280H since that is what you have now but how did the others compare?
