Well since I worked at Tony’s going back to 1966 and for Tony’s former first employee for over 10 years ....
Yes back then it was common practice to tap the 2 side passages under the rear cam bearing and install drilled Allen set screws. It was the preferred method over the screw in the back types.

But we already discussed restricting the oil passages and WTH does Tony have to do with any of this. Nothing and he’s gone so let him RIP

My only point in posting occasionally is maybe to offer some help or make a suggestion from what I see and read.
