When removing upper IM..
 

When you take off your upper intake manifold, what gaskets (if any)does one have to replace when you bolt it back on? Is this easy to do, because I need to get at my injectors.

intake manifold plenum gasket

is this a must, and if it is does a new one seal itself or do you have to apply something to help it seal

yah, its a must. make sure to clean the mating surfaces very well. no leftover gasket material whatsoever. and no, you dont need to apply anything.

Do you know if you need to torque these bolts when putting it back on. I cant seem to find it in chilton manual. thanks...

It is in the manual dude, keep looking.

Found it. For 1987 its 15-22 and 88-on is 12-18 lb/ft. I wonder why the difference.
What is the difference between SEFI and EFI ?

RE: When removing upper IM..
 

EFI simply means electronic fuel injection.
SEFI is the actual "model" of injection, sequential.

Oh, a Ford-ism.

Make sure to go back and check the torque about 1000 miles later. These engines are notorious for shaking bolts loose. I went out to look at mine the other day, and had to retorque half of the bolts on the top of the engine.
