Yeah. took out the #1 valve spring whick killed the valve making major ptv contact. I figured this issue out. Was the cam sprocket. The machinsts spacer he made was too small causing the cam sprocket to be loose. He made a new one and the problem went away for 100 miles, then bam- I have a knock now very loud and sounds like in one cylinder now, but did not lose the power. I will make vid and post it.
It sounds like it could be a bent valve

sounds like a valvetrain problem, why did you rebuild the motor? blow it up?
