Take a guess where the bottle neck is!

Where is the lokar hanging? Idle, I can see that, due to bracket. Top end????

Yeah at idle. I haven't checked it in a while, I "used" to be OK at WOT, but it probably has shifted.

Ok. But the springs are the wear item. As for the cam, if preload wasn't checked when you assembled it, check it. That's what I was referring to.

How do you set pre-load? With shims under the springs? It is a pretty mild hydraulic flat tappet cam, those are relatively maintenance free aren't they (that's why I chose it)?
