The thrust brg ALREADY gets pressurised oil without drilling holes. The escape path for the pressurised oil that enters the journal....is past the thrust flange. If there was zero endplay & no scallops in the flanges, there would be no oil flow out of the brg, no fresh oil able to enter the brg....& it would overheat & fail.

I understand how a thrust bearing is supposed to work, I have also seen several inexplicable thrust failures, mostly in Fords (thrust on #3) one 318 and one 360. This mod ensures a good supply of oil.
