If this is correct, the date code should be late 1991 to 1992. It should be a 1-piece rear main seal block. Heads could have been changed but would have had swirl ports like the c/n 14102193 head originally.
Cobalt, where did you find that? I'm pretty much down to NastyZ28's site, MORTEC seems to have folded again.
