what part number are the studs to the intake to exhaust manifold

Willys Tech:
A564K is the part number you need.

Do the bolts come with the nut that matches them? I just realized I do not see one in the picture. Being as the main reason you would need this bolt is because you snapped off the nut, it really should come as a matched pair.

Willys Tech:
It comes as shown with no nut. I would also order part number: 107823 & 641769. The pal nut and nut itself.

what are the torque specs. for the rod bolts?

Willys Tech:
The connecting rod cap nuts are locked with stamped nuts (pal nuts). Used stamped nuts should be discarded and replaced with new ones. We sell them as well. These locking stamped nuts should be installed with the flat face foward the connecting rod nut. Thur the locking nut finger tight and turn 1/3 more with a wrench.
