Exhaust stud, 8mm x 1.25mm x xx, what length?

[projekt1]

I found what size from searching but no luck on the length. Im in need of two new studs from exhaust to manifold to replace my ARP ones.

Thanks

28mm long.

That would be 2.1 mm right? The smallest Summit shows is 2.5 mm..

No? Am I missing something? WTF

The OEM exhaust manifold stud extends about 28mm (just over an inch) from the head when installed; this includes the complete non-threaded portion of the stud. On the head side, I don't know an exact length, but it is somewhere between 10 and 18mm.


EDIT: The whole stud measures about 40mm, making the portion threading into the head approximately 12mm.
