Matt,
Do the notes below that chart specify to run an intake clearance of .008, if 261 will be used for "severe duty"? I seem to remember reading something like that somewhere...
My Delta cam specifies a .008 intake clearance, which I assume has to do with the lobe ramp design- but am not sure. It definitely makes the valve train a little noisier.
McGurk was running .015 for intake and .016 for exhaust lash in that Soup That Chevy article.
