When does a stud girdle make sense?
Is anybody running a stud girdle with a solid flat tappet cam? My current plan is for a solid cam with around .600 or so lift, and springs with around 135# seat pressure and 350# open. I'm hoping to get away with a set of quality roller rockers. The next step up would be good rollers with a girdle, but at over $500 that puts me close the price of Jesel's new shaft mount system. Basically, I'm looking at around $300 for a decent set of rollers, and around $700 for the shaft system. I would rather spend that $400 somewhere else if possible.
The heads are Dart Pro-1 aluminum. Thanks!

I wouldn't buy the new cheap street shaft rockers. I don't have the article any more. But they stated that you need a stud girdle if your rocker arms have more than .028 deflection at max lift. Not only because your torquing the head stud hole, but because your rocker tip is wiping across the face of the valve stem. Which induces valve guide ware and seal failure.
Your running rather low spring pressure and mild lift so you might be fine. I have a stud girdle because I have too.
It's time for me to go hop in the Vette! :)
