Answer
Hi Chuck,
A picture in a manual would show you. But lacking a manual, look at the manifold ports closest to the valves, and lign them up.
If you are readjusting them, the valves you need to adjust should be loose at that engine position.
Now...I dug out a book for a 1987 2.8L V6, and I will tell you what that valve arrangement is.
They are :
RIGHT BANK(Passenger side)..E-I-E-I-I-E...FRONT TO REAR.
LEFT BANK,(Drivers side)...E-I-I-E-I-E...FRONT TO REAR.
E=Exhaust
I=Intake

Notice they are opposite, because the heads are interchangable, so if you look at them as heads "off the engine", they are the same.

Good luck,
Van
