Thread: Anyone used studs for exhaust manifolds?

Yes they fit... just. Honestly I've been at this job for 25 years nearly and apart from the odd manifold that comes loose every now and then i would stick with the original arrangement. Use antisieze on the threads NOT grease...

Firstly I still have bolts on all my various V8 engine manifolds and have no real need to change.

However - (for 101 or P38 manifolds not sure on 4.0 manifolds) I would consider putting in two studs on either manifold that is in an easy place to get to. The reason to hold the manifold in place so you can more easily get the bolts in - I guess a variation for the 4.0 manifolds would also work.

Just a suggestion from someone who has not done it

Good call Gary. Some Aussie made cars had that approach. It is the 2 bolts at the firewall under the headers that cause problems and can go in at an angle. It and the front one could be studded to good effect. Cheers
