Spend the money up front, something steel or stainless , skip the aluminum as they have a expiration date, run thickest wall pushrods you can with shaft rockers IF its in your budget and you will have a bullet proof vale train , I have had good results with T/D, Smitty

I have used Crower SS and found that push rod alignment will change. Used two rockers to cut and weld the push rod guides.. all the way around the motor. Installed the other 6 pair and the alignment was all over. Roller would not center over the valve stem. Switched to all steel T&D's with the plates. Alignment is excellent. Do it once, and be done with it. Just my .02...

Wish I would of went shaft rockers the first time around. You know the saying spend a little now or a lot later...

What's the consensus on stud girdles? I'm running a .623 lift hydraulic roller to 6000 rpm with Pro Magnum rollers and I'm thinking about adding stud girdles.

Stud girdles and the better arp studs is definately better than nothing, still not a shaft rocker BUT its all alot of guys have ever ran for years and it definately helps, Smitty
