Hello
I am trying to ID my engine so getting the right parts is easier. Most of the time I just guess when ordering engine stuff and get lucky or have frustrations.

This is what the block numbers are:
Casting...3970014
Date K20/76
Stampings: 16S14199
T1216CMJ
Heads: 993's
Several sites say one thing, others conflict, especially the CMJ suffix.

Much thanks in advance, I will attempt the oil pan gasket change next weekend and want to get the right 1 pic Felpro gasket kit.
