I may have screwed up ....more than once

I think we have all had 'mishaps'. I had one I learned from....

I forgot to plug the 1/8" NPT gauge port on a 413 I had just built & was about to fire up......
Fired her up & before I could turn off the engine about a quart of oil went up into the rafters....

As for no oil to the rockers. The cam oil holes have to be aligned with the oil holes in the block to transfer oil to the r/shaft.
