My KB street wedge aluminum block came with bushings up
I would have them added by a good shop so I wouldn't have to worry about not having them.
I have one set of the older special Crane chrome solid roller lifters design to be run in aluminum blocks with no bushings. shruggy
I may end up running them in my new 572 C.I race motor with that block, maybe not confused
