I love the idea of the hole but .250 is WAY too big.

An .0625 hole is plenty, and something around .040ish is ok too.

A .250 hole is BIG!

Edit: I had to LOL when you called a .250 hole a piss hole. That's a classic.

No no no, the pipe plug in the end of the oil galley will get a .040” pisshole. The cam plate will get the .250” hole so there will be plenty of clearance for the oil stream.
