Oh, I don't know. I should have bushed the lifter bores for the taller hydro rollers or for solid rollers from the get go. In the Roller LA's and magnums I don't think they have these problems...maybe RPM limited as compared to solids. I think the magnums addressed the pushrod/lifter angle too...don't quote me on that. I might take this one and have it bushed for a rebuild on the stand ready to go should I toast something on the track with the new factory LA roller. I just need to figure out which solid rollers work with the magnum style lifter bosses. Something EDM and a bushed roll .800 if I can find one. I don't know if the hughes cryo would stop the galling...I aint gonna find out either. There's a lot of retro roller LA's running around out there...I think mine may have already had worn lifter bores to start with. I do know my closest lifter oil band to being exposed by the bore chamfers is about .060 thou. It did seem to weep more than I anticipated at the lifter bores when I was priming it after rebuild.
