So with farther inspection turning the motor over by hand with the cct set the cam chain changes tension. It gets pretty sloppy at one point. The only thing I can imagine that would cause this is side to side movement of the cam gears.

What would cause this? Well warped camshafts could. Warped cam caps could. A seriously warped head could.

How would you check what it is? I don't really know. The exhaust cam has a tiny bit of coloration on it, so it must of gotten hot.

The right thing to do would be a new head, new valves, new cams, new rockers, new cam guides, etc. However being that would cost a fortune, I will likely buy a head assembly from eBay. I found on for the tune of $100, not sure if it includes rocker arms. I might buy it, hook it up, see if it works, and if it does just tear it down and rebuild the head, clean it up, port, etc when I bore the cylinders out.
