Hi Bob.
You will find that a lot of cam timing is done with 20 to 50 Th just for set up depending on the camshaft manufacture ,
then revert to recommended running clearance.
Your other comment on quick lift lobs a lot of these run roller followers and the tip of the lob has a bigger radius they also require stronger Valve Springs
