Slant 6 timing chain lubrication?

Fantastic choice for a timing set! Most people cringe when you recommend the Rollmaster set because of the price. They are worth every penny. Here's the trick to get pressurized oiling right on the timing set. See the pipe plug I circled in red? Drill a .040" hole right through the center. That's the main oil passage. It will blast oil right on the timing set. I wouldn't go any bigger than about .040". That way, there won't be an appreciable pressure loss, but you will SOAK the timing set and that's what you want. I'm doing both the main bearing chamfer trick and drilling the plug on mine.

I did the same with my 273 although I drilled into a Welch plug (soft plug) and it was a 1/16". Probably too big but no issues, and that .040 drill would be much better.
