Years ago, RAS sold rocker shaft pedestal shims to correct rocker arm geometry. Unfortunately, they have not been available for some time, so...I've been looking around and wondering if anybody knew of any shaft shims being made or available? Thanks...

I used to love the tapered shims--hate we can't get them but....I have used dozens of sets of home made shims over the years--always with stamped rockers and hyd cams--I have never split a stand. I understand the math and all but they work on regular old street engines vs. ordering expensive pushrods. Yea I know about geometry but on a stamped rocker the pad is plenty big enough and correcting lifter preload vs. having the plunger down is a big big deal even on a Plain Jane.

The last ones I bought from Mancini were NOT tapered. The last time I bought shims from Hughes they were, but they'd stopped selling the .060"-thick ones and were down to only the .020" and .040", IIRC. That was years ago and I have no idea what they sell today. Not sure if I have any of the good ones left, either unused or used. I'd switched from stacking the tapered ones to having a nice set of thicker parts machined by the late Dan Costello a few years ago, and may have pitched the rest of the shims after that.

I called and had an interesting conversation with Michael at B3racing today and that's the direction I'm going with this project as it's more than just 'a few shims'. Check out his tech article on rocker arm geometry and Jim Miller's page as they go pretty much hand-in-hand. Great info and I'm sure many Chrysler racers and builders here on moparts would benefit from this correcting their geometry as well.
If it took more than .060 to get it right I milled the stands off and made up new bolt on stands like the race heads use... my W-5s I had to mill the pads down for my TD rockers.. my W-9s were real nice
