my exhaust manifold studs are shot and I'm looking for new ones, you guys got any suggestions on where to get some and what kind
 
Advanced auto parts. I think it was for a ford but they worked great and had locking nuts included. They were in stock on the shelf just ask for them. Should be the same at any auto parts store.
Just ask where they keep the exhaust manifold studs at then match one of yours to the one you need.
 
When I swapped heads on my car, I did the old-school way: Parts lookup in CAPS and then went to the local Dodge dealership and ordered them! Stainless steel studs would also be awesome as well, from FFWD or any other place listed in the previous responses.
 
I have the copper ones. They have the lock built into the nuts so there isn't a separate lock washer.

Oh ok, thanks. I guess that means that the copper ones aren't reusable? I was wondering if there were some sort of thermal property that would make copper better. Or maybe they have a better corrosion resistance. Although the stainless ones seem to be a high grade stainless.



I'll be sure to pick up a set when I install my fp manifold sometime in the future. Thanks for the recommendation.
 
The copper nuts shouldn't be reused. That being said, I'm on my 2nd or 3rd time reusing them as I always forget to pick up a spare set.

Why not send Jeff an e-mail and see what he has to say on the copper vs. stainless and post it up here?

That is a good idea, I wanted to ask him a shipping question anyway.

I'll update when I get a reply.

-Edit-

Here's his reply about the differences between the nuts:

--------------------

"The copper plated vs stainless is just mainly an option for two camps...
Some people like using lock nuts, since we are using stainless studs we can't use stainless lock nuts (the threads of the two would gal, making them near impossible to remove). You never want to use a locking thread on a stainless on stainless fastener. So in this case we offer the copper plated lock nuts as a locking nut option since it is a dissimilar metal and looks nicer than the regular yellow passivated finish you'd find on most plain carbon steel nuts.

We also offer the stainless nuts with a locking washer for those that like the all stainless look, and they work well if up remove your manifold often. Locking nuts lose their "locking" capabilities after frequent install/removal, unless you deform them again manually.

So after reading all that, it is personal preference. "

He wrote an informative response back, I'm going to order a set.

There's a reason why no OEMs use stainless studs or bolts with aluminum parts.
