I have been looking and looking for pics of my lifters out of the engine to no avail. These would be 3772-LO-180 w/ EZ-X Roller Option. There is a label indicating they were assembled in June of 2015. They were for sure the solid body and had a hole feeding the axis of the roller bearing. That I remember.

Also, my cam is a 1.050 base circle. Doug, do you happen to have the base circle of your cam handy? Could that have something to do with it as well?

FWIW I have had no oil pressure but that was only 20ish dyno pulls.
