My current cam called for .014 and that is what I run it at, hadn't messed with tightening it up any. This is an all iron R1 W2 combo so I don't compensate for growth and just set them at .014 cold.

My cam is supposed to be .734 .747 at the valve with 1.6 rockers. What I measure at the valve is .645 and ,668, I do not believe this number includes lash. I measured lift at the retainer to set spring height and left a little wiggle room in case I wanted to tighten lash in the future. Pretty horrific loss that probably messes with timing a fair bit also.
