If you are not 100% sure how to degree the cam with that gear drive PM me and I'll walk you through it. It's not hard. In fact, it's so easy once you get how to do it, you'll laugh at how simple it is.
BTW, gross or net lift has little affect on V/P clearance. It's valve opening at TDC and just after TDC that makes clearance issues.
I'm betting you are off a bit on cam timing. The Milodon instructions are a bit on the vague side. I was going to do a video on it, but, like lots of other ****, I never got around to it.
