TC, thanks again as always. I took some photos and have some answers for you. Here is a link to the photos of the block. From what I can tell, one port has a plug in it, and the other doesn't.

The engine code is 3836340, which I think is an early 55-57 motor, but if somebody could help, it would be greatly appreciated. Also, I couldn't find a dowel anywhere on the engine to push in / out. I guess this wasn't an option for this year? Anyway, some oil line routing would surely help. Os should I just plug them?
