I'd much rather not do that, this Magnum short block is in mint condition and I don't want to touch it. I'd much rather fab a custom oiling system for the rockers than go through the trouble of finding another block which I doubt these stock Magnum pistons will fit in, it's really hard to find "virgin" SBM LA 360 blocks nowadays... then I have to worry about honing (at least), rings, etc.
