Anyone running stud mount rockers.

Dark_5.0 · 03-03-2002, 02:33 AM

I got a really good deal on stud mount 1.7 roller tip rockers.......The only problem is, no studs........I cannot find rocker studs for my E7's anywhere.

What's the deal. The guy at the machine shop told me "You will need to get pedistal mount rockers for E7's"

That doesnt seem right to me. Any help would be appreciated.

Thanks,

pulled a fast one on you, stud mount are for trickflow heads, the guy is right, you need pedistal mount rockers, not stud mounted.

who sold them to you? was it the machine shop? sell them to someone else, or save them for a head that requires them if planned in the future.

Can you not just screw studs in where the stock rocker bolts go.

You may be able to convert them, im not sure, wish i could answer that, hopefully someone will wake up and help on this topic, a good question though.

I remember a while back my brother wanted to do this same thing. All that's involved is getting studs, guideplates and hardened pushrods (from a local speed shop, they may even know who'll do the work), and have the machine shop machine the pedestal mounts to work with the studs and guideplates. I wish I could help you more, but I don't remember the part numbers or anything like that... I do think that someone like DSS or Coast High Performance made a stud mount conversion.

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.

Crane Cams sells the conversion, no machine work and you can use your original push rods. Jegs and Summit both have it in the catalog. It cost around $125 and is worth it.

Thanks for the replies, I will look for that kit in the summit book.

I used the Crane conversion kit to put my stud mount rockers on the stock heads and it worked fine. It's worth it if your gonna keep the stock heads for a while. I had mine on for 2 months and bought new stud mount heads. Doh!

The conversion kit is OK, but its a bandaid. If you're planning on making much more than stock HP or revving the engine more than once in a blue moon, I'd recommend against it. Its just not very stable compared to good 3/8 or 7/16 studs. For the $125, your machine shop ought to be able to do the machine work then you'd only have to cover the cost of guideplate and pushrods. Money ahead IMHO.
