@buoymaker, i had squirted brake/car cleaner down the tube when I took the rocker arms off the 1st time. By the sound of it draining into the pan, I think its clear. Last time it was running, it showed some oiling trying to happen. The weep holes were trying to dribble, but nearly all of them were plugged up. I think they will work properly now.

Today, I'll be visiting with a my brothers neighbor who has a 53 and has offered to give me the 216 out of his truck, for parts. It has a cracked block, but has many spare parts I could use....for just in case.
