rocker arms Stud or Shaft, Crane or Comp
in the process of finishing my 540 SCI builds. Now looking into rocker arms type and styles. I have Comp Cams Ultra Pro rockers and several sets of Crane golds. Which ones are best for Hyd. roller .60 lift? Also when is a good time to go to shaft mounts like Jesel? Going to spin engines to 5800 RPM.

Skip both of the brands you listed. Crane Golds are not as good as they used to be. Buy the Scorpion Endurance Marine Lifters. These are the same as what are used in all Merc Blue Engines.

(775) 884-2292 T&D Machine products. Call them directly, they are great to deal with and will be able to sell u a shaft rocker system thats built just for your brand of heads
P.s.- go with the 1 piece intake stand systems instead of the individual stands, and once you set them all up get the exhaust stands welded to the intake stands. Then you will have an extremely stable and solid valvetrain.

I will never buy anything but the best of the best for my valvetrain components, when cheaper **** breaks it costs much much more in the long run to fix what gets destroyed when low end parts break.

at 5800 rpm, shaft mount rocker arms are overkill.
a good set of crower or comp cams hi tech will give you 100's of hours of trouble free operation!
if you want to spend three timrs the money then t&d is a great way to do it but, unless you are spinning the engine to 7000 and have monster valve lift and high spring pressure, you don't need it.
t&d is super stuff! on an all out high rpm race engine, it's money well spent! on a relatively mild mill that will never see 6000 rpm it's money wasted!
