The may be a tough one but does anyone have an idea of what I should torque my rocker studs to? got some Harland Sharp 1.7 stud mount rockers and want to put the studs in today.

Thanks Chris,
After searching around, I saw this thread and I am tempted to go with what it said since the guy said "per his AFR manual" Also should I use Threadlock or anti-sieze considering this in on my aluminum heads? I dont have any experience with aluminum heads (obviously) and dont want to mess em up.

Are these pedestal mount heads, that you're using a stud conversion bolt on? Or are these stud mount heads?

If they are originally drilled for pedestal mount rockers, use the tq spec's Chris provided. If they are stud mount heads, use the 60ft lbs, which btw, is same for TFS heads.

Hope this helps.

These are stud mount heads to begin with. The heads came with 3/8 inch studs and the rockers I picked up are 7/16. What about the anti-sieze?

No clue on the antiseize, I cant remember if I used it or not... You DID get diff studs to use with those 7/16" rr's, right? hehe.

Go for the 60ft-lb spec, and I'd say put a DAB of loctite on them. Ask Ben about that... hehee.

Dont worry Fred, I aint that stupid!:) The heads came with 3/8" when I bought them. When I saw the 1.7s for sale at FFW all the had were the 7/16" stud and told the guy I would buy them if they were 3/8. So then he said " well what if I gave you the 7/16th studs for free?"....cant argue with that!

Trevor,

I don't have a set of AFRs in front of me (but it would be cool if I did..LOL), but take a good look at the bolt holes before you install the studs.

Some heads actually have that hole drilled far enough down that it protrudes into the intake port. If this is the case, you need to seal the threads with something (preferably Loctite PST or equiv). If the bolt hole doesn't protrude into the ports....carry on and ignore this.. :)

Good Luck
