A couple years ago a new set sold on ebay.  For some reason I was thinking of them and wondered if anyone here picked them up, and if so how they worked out.  Havent seen another similar offering since.  Or, do some of the veterans have past experience.

I have a set of the Thomas magnesium rockers at Ted Eatons now for rebushing and testing. May not be good for the street though. Maybe Ted will chime in here. Chuck in NH

I’m still working on those magnesium Thomas rockers of Chucks.  There were at least two different rocker ratios available for the Thomas rockers so you have to watch out for that if you’re obtaining partial sets of these from different locations.  The magnesium itself doesn’t wear well against the shafts so they would be a short life rocker without bushing them up front.

Many Moons ago, my Buddy's 56 Gasser had Thomas rockers briefly. For whatever reasons, possibly oiling problems, although there was no sign of that with stock rockers, one rocker snapped off.. He went back to stock rockers, which worked fine, even at up to 6800 RPM.
