Tight lash setting solid flat tappet cam

Like anything else, there is a diminishing return. With lash that tight, you are making greater changes in lash as a percentage with small moves than you are with a cam that lashes at say .028 o some nasty valve train crashing lash like that.

YR, Mine called for 28/32 cold. I run it at 24/28 and have never had an issue.

Are you saying you think I could go tighter that that?
