Buddy of mine is thinking about upgrading to a 1.6RR (Comp Mag 3/8") on his LT1, they are non-self aligning therefore he should get a set of guide plates for them. He is going with the Trickflow TFS-30400623-8 guide plates. I read somewhere previously that you need a longer length stud due to the length used by the guide plate. What rocker arm studs are people using for this application?

Thanks in advance

 

I would contact http://elliottsportworks.com/ (Lloyd Elliott) he can guide you in the right direction

 

Also, if buying new rocker arms, always upgrade to 7/16 studs and arms.

 

Do the 3/8" studs tend to have issues? Or does it just make for a more 'stable' valvetrain?

 

Significantly more stable valve train at rpm. Check out Engine Masters, they did a comparison with clear valve covers.

 

The 7/16” rocker studs are more stable. Higher valve spring pressure, more aggressive lobe ramps, higher lift, and higher RPM may make the 3/8” studs unstable. Cheap insurance. Alternatively, you could use a stud made of stronger steel (e.g. chrome moly)

Interesting notes on stud selection:

Great info, I'll have him keep that in mind.
