Anyone running stud mount rockers.

[Jeff Chambers]

Your heads will need to be machined to accept studs AND guideplates. Any decent machine shop should know how to do this as its a real common machining operation for Ford heads. The instructions & dimensions should also be given on your instruction sheet for the rockers. They can also be found in the back of the FRPP catalog. You'll need to buy some guideplates and hardened pushrods. With stud mount, there's nothing to keep the rocker from pivoting around the stud and maintaining alignment of the pushrod & rocker relative to the valve tip. So you use guideplates to keep the pushrod located which keeps the rocker located. You need hardened pushrods to keep them from wearing as the rub on the guideplates. Isky makes a real nice adjustable guideplate that works with the SBF heads. Comp Cams, Isky, Crane, all of the biggies make hardened pushrods for use with guideplates.

Stud mount rockers are great for adjustability and they're alot more stable than pedestal mount. They take minutes to install and adjust compared with the hours that can be spent trying to get pedestal mounts set up perfectly.
