What size are the exhaust manifold studs for the 2.6 engine? I have a new head and want to put all new manifold studs in.
thanks guys

To save the stud head threads (especially the back one), make sure you cut the webs on the exhaust manifold, and have the manifold surfaced flat on the head side gasket face. Cutting the webs is cutting the gasket face of the casting so that each exhaust runner and it's two bolt holes are isolated from it's neighbor(s). I suggest a Sawzall and about three short metal cutting blades, or a good whiz wheel. This is a very necessary mod on turbo manifolds, and a good mod on carby mani's. Also helps prevent manifold cracking from heat cycling stresses, esp. on the turbo.

If you have access to a non-wife controlled oven, also try heat baking the mani at 500-600F for about 12hrs, then let it cool slow (leave the oven closed until cool). This will relieve stresses in the used manifold. Have it surfaced afterwards, as most will move a lot as they relax. If you have a wife, and you use her oven for this, you're on your own, and I won't send flowers....

I just bought exhaust and intake studs since i am replacing my 2.6 head....
Go to automotivefasteners.com....
They don't have online ordering but they are very nice on the phone....
These were very hard to locate, but this place sells an exact match...
Their phone # is 800-632-0340.......
Check out the link below for the stud size....<img src="/forums/images/graemlins/cheers.gif" alt="" />
Exhaust Manifold Studs

The thread pitch is 8 x 1.25 mm the lenght I'm not sure about.

I replaced all of mine during the rebuild -- I just took a stud into the local hardware store and matched it up. The one they had on the shelf was a perfect match and was inexpensive. Of course, our local hardware store has three isles of blots/nuts/studs and it's uncommon not to find even rare fasteners there. It's completely locally owned, not a chain. Terry

Thanks for the replies. I bookmarked the catalog and printed out their stud specs. I am going to check locally as I am going to try and change the head today.
