I wasn’t aware of that but each one held (did not leak down). One plug had a little oil on it (in a picture). Even with 1 plug out the motor cranks up & runs very smooth. Also the oil pressure stay up.

It cranks & runs great if a little rich still. I got a 1 barrel Manchester I could put on if needed.

I guess I’ll just drive it for a while. I can’t pull it out & apart again!
