No, the cage doesnt have a oil hole in it... just uses
splash to oil it

I have a fixture that drops into the lifter bore and
you drill the hole through it(MP sells one) but their
hole is larger... I made my .060... the lifters have
a hole for the axle and the push rod oiling

Something like this........
I used the M.P. fixture with a #2 center drill , then opened the holes to 3/32nds. .09375 after I got the tip of the center drill to locate and start the holes.........the holes in the fixture are .125 as I recall.
.060 is all you need , but I wasn't comfortable using a bit that small with the angle and a hand drill.

Yeah I have one like that... I took that design but
changed it a bit... I used a electric pin drill to
drill the holes but I was just drilling the bushings
