Valve lash compensation

Running that same cam in "Georges" Cuda, and set clearance at .018 / .020. You're wayyy too loose on your setting!
I’m going to tighten them up.
You run a vacuum gauge ?
If so what kind of vacuum at idle in gear you have?
I also found more issue with noise this morning. The Cranes have way too much side movement.

Going to order some shim rings today.
