OK, I am confused about the end hardware for the exhaust manifold. I see pictures of the install with the slotted part of the net facing away from the washer, but I have removed plenty of them with the slotted part of the nut facing the washer. Which way is this really supposed to go - slots up or slots down?

Slots down toward the washer. The factory nuts are not a "normal" locking nut. They don't lock until the slotted portion fits into the taper on the washer, then the washer taper squeezes the nut onto the stud,

Thanks Charrile, That's what I had always done.. But was unsure if it was correct.

Referring to the attached photo, the pair on the right is directly off of a slant six in a 1983 Dodge truck. The washer has a straight center while the nut has an extra tapered edge to fit into the washer.
The one on the left is aftermarket, the nut is straight (no taper) and the washer has a bevel in the center for the nut.
I am just wondering if the aftermarket one will work as well as the OE setup because the factory style nut is impossible to locate.
