Selling a complete set of small block PRW Platinum adjustable rockers, shafts, spacers, collars and hold down clamps; everything you need but the bolts. Mike at B3 Racing modified the rocker shafts and made a “geometry correction kit” set of shims for me. The shims are for use with Trick Flow heads but I believe the set works with stock heads by not using the shims, Mike at B3 could clarify. Also included is a box of additional PRW spacers, collars and hold down clamps, which I bought separately. I purchased all of these last year, I need to sell off some things. There is nothing wrong with these, I only put 200 miles on them after a complete engine build. I will be listing separately the Mopar Performance hydraulic flat tappet lifters and Smith Brothers push rods I installed at the same time, also with only 200 miles on them. $300 shipped anywhere in the USA from Alaska.
