Well, I got it plugged. The pressurized line seemed to be 3/8" x 27tpi that connected to the small comp. fitting going to the gauge line. The return & head holes fit 1/4" pipe plugs just fine; now I know why as well. I pulled the rocker cover to make observations.

I get about 30-40psi on the gauge but no oil out of the rocker holes . Now to get my hands really dirty.
