who is running MRL (BAM) Lifters without lifter bore sleeves

you can go to ford size adjusters and best to have the cup on the adjuster and ball and ball pushrods
the pushrod ball should NOT rub on the ball tip in any case the wear should be a band down from the tip- does that description make sense?
if there was pressure on the tip it would be tremendous
good point on the reliaility of chevy and SBF and all the other oil through the pushrod applications
