Bill,
I saw John's cam after he pulled it from his rebuilt engine. It was the dizzy gear that was trashed. The rest of the cam was perfect. The only reason we could think of for the gear failure was a HV oil pump and the lack of the galley plug hole.
John replaced the cam with JimBs first flat tappet cam design and a drilled galley plug. He also installed a new OEM dizzy gear. That same engine has now been running well in his coach for over 50,000 miles, so I would have to assume that drilling the oil galley plug prevented any further issues.

It is obvious that each different combination of parts will provide different results. That is evidenced by the success and failure stories we read here. Drilling the galley plugs shouldn't cause any negative effects, but it might prevent some. YMMV ;)

> Yes do not run the engine without the hole. I picked up a 455 a few years ago as a fresh rebuild with scrap cam 40 minutes of running with no hole in the plug. This engine had all the right parts but was probably built by a Chevy guy so ended up saving a bundle on machine work.

>> How important is it that there be a .03 or .04 hole drilled in the aft oil galley plug for extra dizzy gear oiling like Joe Mondello insisted? Reason I'm asking is the crate engine I just picked up doesn't have a hole in the plug as it was built from the '70's book. Should I pop the plug and drill it? Thanks in advance, Woody

Flat tapper cam break in is a crap shoot now without zinc and knowledge about proper cam break in procedures. I know many builders that won't put an engine together unless it has a roller cam. I don't think cam lobes going flat had anything to do with a oil plug not squirting at a distributor drive gear.
