Sounds like u did something wrong, I`m running un bushed lifter bores, and mrl solid rollers and it is working fine , other than a little low hot oil pressure at idle Clinteg is too !
Ahhhhh, with all due respect, I did nothing wrong. The Kit came complete from Mike, I assembled it, yes the cam bearings are in correctly. I have put many engines together over the years, I am 60 years old...not 17. It fired right up and ran great...for an hour. If I did something wrong...it was me not doing any oil mods, but I was told by Mike that it wasn't necessary.
