Same here. Valves a hair right for my liking. But otherwise good. Mine are the CNC Shockers. I widened the pushrod pinch with a brass tube insert and a minor trim for the gasket. Otherwise, they were really very well built.
The valve springs don’t meet the requirements of the cam I’m running. So they were swapped out for the cams matching spec requirements. Not a big deal. Valve spring heights were spot on and rechecked with the stiffer springs.
The B3 racing geometry correction put me into the pushrod clearance issue. I'm running 1:6 PRW rockers and hardened shafts. I told Mike that I can elongate the shaft hold down bolt holes for the geometry correction and he laughed at me.
