I don't know if this will help you, but my 1994 Z34 with the 3.4 DOHC motor
I would take the top front engine mount off and put the bolts back in place.
I would then take a turnbuckle with a hook on either end and crank the motor
forward about two inches. I could then get the wires off and plugs out of
the rear of the engine.
The plug wire boots are about 8 inches long and rigged on this motor due to
the plugs in the center of the head.
There is no special tool required to remove the heat shields from the spark
plugs, just pull them off with your hands when they cool.
To get to the three back plugs, just unbolt the motor mount in the front top
(looks like a dogbone) then get in put the car in reverse and put on the
ebrake then give it a little gas till you see the engine move towards the
front of the car, then put it in park without taking your foot off the brake
This is how I usually do it, I dont know how a real tech would do it, but
its gotten the job done for me several times.
