Found a fun surprise from the boy. He'd swapped adjuster nuts for the #3 cylinder intake and exhaust rocker arms, which resulted in the intake staying open, so it had 0 compression.
So I backed them out (they're hollow nuts with a threaded-in jam nut), got to near 0 lash, and tightened the jam nuts down, and it was immediately 150 PSI. The rest of them are all 148-153PSI, so I think I'm good now. Ran much smoother on 8 than 7, lol.
