Post subject:  Intake/Exhaust stud specs?

I sent my head to a shop to get reconditioned and they had to remove my intake and exhaust manifold studs to fit the seat and guide machine. When I went to pick it up, the studs had been pitched. I know I can get these studs included in the ARP head stud kit, but I don't want to use head studs. I just want to know the lengh of the studs and how much thread is on each side of the shank.

Any help would be appreciated.

Thanks,

John

I'm not sure, but the last time I replaced the intake/exhaust manifold gasket, the studs looked to be sticking out about an inch and a half, more or less. On the threads, I would guess that they go from the tip of the stud almost to the head.

Oh yeah, I read here somewhere that carb studs are the same as slant six intake/exhaust manifold studs.

Reed had this same question about a month ago. See if he found a solution.

Manifold set to Cylinder Head Studs are 5/16-18 unc x 1/2" thread length (head side) by 5/16-24 unf x 3/4" manifold side.
The factory stud was 1 7/8" in total length so there was about 5/8 inch of unthreaded area between the two threaded ends.

Many of today's replacement "aftermarket" studs are either a little long (2 inch total) or a little short. (1 3/4" total) The thickness of the "spanner washers" to be used, will help decide on which stud to get.
The machine shop that "tossed" yours, should get you a set of replacements.

I just tried to order through their website and couldn't. Called the toll free number and the lady said I was her 5th complaint today. I just ordered over the phone. 36 studs @ .50 each. :D

Thanks for the link! 8)
