Thread: Exhaust manifold studs

Wanted some options for new studs.
Of course there is oem.
I know so far they are 10mm x 1.25
Not sure on length. But the aftermarket cant be any longer or it would hit the manifold i have. I saw the enjuku that ben has, and notice they are longer.

Any one know of a ARP option or similar?

You talking about these?

ARP 400-8012 Stainless Steel Exhaust Manifold Kit 8x Studs/Yokes/ Nuts

I have to say, the OEM solution seems to work better and is cheaper than the Enjuku manifold studs. I didn't even bother to transfer them over to my latest engine. The Enjuku studs come with locking nuts that don't come loose easily. Instead, the entire stud backs out when you try to remove the nut. Kind of annoying. They are stainless which is nice, but anti-seize on the stock stuff is my current preference. Or at least use the OEM washer and nut, not the Enjuku supplied flare/locking nut.

Blair, those don't seem to be the right size. He's talking about the studs that go into the head by the exhaust ports.
