Oh, now I got it! Thanks guys, that explains it. I'm a bit thick sometimes ;D
I did use a ton of that red startup engine slick on both the crank and the camshaft, but I didn't think of the cam not getting lube from a low rpm turn over. Makes total sense as to why you want to start it and run it at high RPM the full 20 minutes, right off the bat without much cranking.
I have to pull the oil pan to rebend that oil pump arm, so while I'm under there I'll take a look and see if any of the lobes are noticeably damaged. Even if they aren't, I see now why you're supposed to keep turning to a minimum before startup. Good information to know, thanks guys.
