Ummm...The 85's are probably harder to find?
Only thing I can think of that might be different would be the EGR passages...
They have the o-ring grooves just like all the rest of the 13B's, right?

HELL YES THERE IS A BIG DIFF. 1st gen irons did not have o-ring grooves, the rotor housings did. 86 and up, the o-ring grooves are moved to the side irons. You cannot mix-n-match for that very reason.

Yeh, but he's not talking about the 12A's...Did the 85 13B's have the 12A's o-ring grooves?
We'll have to wait for a guru for this one...
What about the port air system passages on the 85 vs. the S4's?

well i ripped apart a gsl-se motor today, and the water orings are on the rotor housings not the irons. the gls-se motor had the egr blocked off, but other than that they are the same
