Yes Rich, I agree, more clearance at the exhaust would be desireable.
However, the engine seems to have responded VERY well to the "late" cam. Above 6000 is a different animal all together. Also, it's of course a stick car, and never sees below 3500 at any time during a run... and still has a terrible traction problem.

Hans, I check piston-to-valve by the "light spring" method. My "close" spot,is about 10- degrees before TDC on the exhaust valve.

oh yeah... it was an intake lifter... hot clearance had been set to .014" ( .016" hot by the cam card from Comp )
