Figured out my cam issue. I think I accidentally switched the shims when I first took it apart. The "heel" of the right intake lobe (non-lift period) was starting to hit the lifter. I guess this would mean beyond zero clearance. Switched the shims left to right and problem was gone. Now the cam spins freely with the holders torqued. Talked to Agent Smith and they said my valves are probably at their limit. I shipped the head to them early this week, so I'm waiting to hear their thoughts.
