Just for comparison purposes, my partner put this cam in his '78 B engine
(which is otherwise stock and has all required California emissions
equipment). There were no problems with valve-to-head clearance. There is a
problem (if you consider it such) with much more valve noise; he's adjusted
them to both the suggested clearances and to tighter clearances, but the
engine still sounds like a threshing machine. As to performance, there's a
bit more mid-range than with a stock cam but nothing to get excited about.
