Title has what I want. I'm mainly looking for what will work from the 79 to the 93, that's the spare motor I have. I've seen the valve cover gasket is different, looks like the bolting holes are spaced differently. Oil pan aswell, though for a 81 with the rear sump dipstick. There's also something about a 95-96 rear main seal fitting as opposed to the rope seal. Outside of the stuff that bolts on top and below everything should be identical? Everything besides the pulley system anyway.

If you guys are curious, my 93's L6 had a prior head gasket issue (undisclosed at time of purchase) and developed into a cracked head, trashed all the bearings. 79 L6 was the best motor I could find, with only 99k miles, but since it's not in a truck I want to redo every seal.
