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

I was running MRL lifters for about an hour, Low oil pressure, burned up Hughes rockers on passenger side over hole #2. Everything is a big mess. The shaft on the passenger side is scarred so bad it looks terrible. Mike said these are drop in, no mods needed. Wrong! I really don’t know what to think. All components were purschased from Mike. I assembled it all. I was running a solid roller VooDoo cam and the MRL lifters with Smith Bros. Push rods, and Hughes shafts and 1.6 rockers. Disaster. It is my opinion after doing a lot of reading that the lifter bores should have been bushed: bushings installed. Or at least the galley needed to be tubed and peened. Live and learn, expensive F up.

Pulling engine, going to take it apart. Either I’ll have the lifter bores bushed, or possibly buy a set of Comp 828-16 lifters (no oil belt). But these lifters require grinding the block, should have been done before it went together.
