Well last night I broke a rocker arm stud.im just wondering if my valvetrain is good enough for my setup. My engine is a 383 le2 heads the cam is a 234-236 565/565 110lsa that's with 1.5 rockers I never figured out what the lift would be with the 1.6 rockers. The rockers are 1.6 sa comp pro magS, the studs are 3/8 studs, patriot dual gold extremes valve springs, and ls7 lifters.
Should I upgrade to a 7/16 studs, guidplates,and NSA rockers?

 

Absolutely Mike. 7/16s + NSAs are where it's at.
