With all those B1 parts, you must have been doing the B1 heads for a long time.
I wish the drain back lines could be above the oil level. For less chance of oil seepage at the fitting hole.
But with the location of the factory weld on the Milodon pan, I think the holes will be below the built-in windage tray.
