I wish,  it's either a valve/valve seat contact issue or weak valve springs.

Did a leak down test, 20% leakage through the intake valves, pulled the head to see if I could lap them in but was not successful. The head is at the machine shop getting the valves and seats cut. Should only take a week or so. Then back to all the checks before dyno tuning.
