While running my engine on the test stand the engine made a funny sound at which point I pull the heads and found this.

It always sounded like the engine needed the valves adjusted. I then turn the engine over by hand with the pistons and cylinders removed. Ever now a then the engine would be real hard to turn over then it would be easy, with help from John Jentz he notice that the case had shinny spots on the lifter bore after putting the cam back in the half case with a piece of paper between the case and cam there was no clearance and by pulling the paper out the cam would rotate! I then check all the loop clearances, dam they all had the problem. The cam that was installed was a SCAT C35 high lift cam. So beware if you install a high lift cam made sure you have clearance between the cam and the case.
