Lean pop off idle?
I didn't say a single word about whether that cam is; good, bad, or whatever. Nor did I suggest to replace it. All I said was;
I don't like that cam one bit.
and the reason I said that is because of exactly what it is doing in this particular combo, and what it will continue to do.
BTW;
the Wallace Calculator predicts;
at a true 9/1 Scr, cranking cylinder pressure is likely to be ~130psi, which is pretty Low Compression.
At 8.5 this drops to ~120psi which is nearer to Miserably Low.
