Stud girdles for narrow-body rocker arms?
I have some Edelbrock Performer RPM heads with Scorpion narrow-body roller rockers. First question, are stud girdles a good investment? And second, if so can someone recommend some that will work on the narrow body rocker arms? Everything I can find seems to fit a minimum width of 0.600" and the Scorpions are 0.530". Thanks.

Re: Stud girdles for narrow-body rocker arms?
What kind of open spring pressures are you running. Less than 500 pounds and I wouldn't even bother with a stud girdle. I don't even know if those heads use single or double springs. You shouldn't need a stud girdle until you get close to needing triple springs but by then you're getting close to needing shaft rockers instead.
If you have a high spring pressure double spring, upgrading to 7/16" rocker and stud would be better and easier.
