Are stud girdles legal in Stock?

Without stud girdles, if they allowed full roller rockers in stock, the first thing that would happen would be a lot of engines with stud mounted rockers would start breaking rocker studs.

In most cases, where the old school style rockers are used, the rocker arm is the "fuse" or the "weak link". Changing to aftermarket roller rockers will merely change what part breaks first. Then the people breaking that part will demand aftermarket versions of that part be allowed, or some sort of device designed to prevent breakage be allowed.

Yeah, I'm one of those guys, who thinks Stock Eliminator has already moved too far toward Super Stock.

Alan,not disputing what you say but in my original gremlin i ran a 390 with 7/16"studs,crane rollers w/poly loks,guide plates with a .510 lift cam.Granted the duration wasn't very aggressive at .232 @.50.I put over 3600 runs on that engine
with two puff ups and new pistons once.Shifted at 6000 rpm.I never broke a valve train part in all that time.Colud the aggressive cams we run be the culprit?
BTW the car ran as fast as 11.20 122mph.Tight converter I'de say.
