Help with Valvesprings and valve float. Noob

FWIW.... I am pretty sure the OP has the PRW PQ rockers. The needles are short length needle bearing assemblies, 1 pressed into each side. So you take them out and you have a recess in each side, with a smaller ID 'step' in between. So you have to bush them with 2 short bushings about .375" long on each side. Or machine that step out in the inside... not worth it IMHO unless you already own a mill. Probably not what most think of when they think re-bushing.... as with one long single bushing.

(I'm gonna re-bush my PQ's with 2 bushings per rocker, but I won't put them in harsh use. I expect to make a jig for them to make sure the 2 bushing are exactly aligned.)

If you were to go with two bushings pressed in, the correct way to do it would be to ream them to size after pressing in. That assures alignment and sizing. I don't know that I would bother with a bearing length that short. If you can't bore them yourself or pay someone to do it to do a one piece full length bushing, I'd sell them as is and put the money towards something better. Just not enough bearing length to support anything but a very mild spring, IMO.
