3/8" stud? 7/16" stud? NSA or SA? I'd just replace the rockers and springs...

Again I am more leaning towards doing the suspension, but possibly the rockers could come next.

 

If you are going to do a cam/heads package in the future, make sure you get the stall you will want then so you dont wind up buying too. 2600 is kinda low if you were to use it with your h/c cam package. Save your money, and do h/c/converter @ once. If you must have it now, do the converter, maybe a 2800. Just my .02

 

They are 3/8" and SA.
