How to tell 13B / 84/85 and 86

Looking for a definitive sign to tell the diff in 84/85 GSL-SE 13b's and 86+ 13b's. I can not use the front cover to tell, so I need another way.

Intake manfold is totally different. 86+ 13Bs have 4 inectors.

Intermediate housing is different as the 85- 13B will not have the mounting holes in the bottom. The 86+ 13B oil pan also has a notch in the passenger side for the engine mount.
