sorry for too many questions..
i'm trying to remove the manifold looking at the instruction below but it won't even move a bit. Is the instruction missing something?

Removing the Manifold

Looking at the top of the engine, there are six bolts in the center that secure the manifold gasket and two screws (one in the front and one in the rear of the manifold).

1. Using the 10mm socket, remove all bolts that secure the manifold gasket. Place the gasket and the screws together away from the car.
Loosen and remove the two manifold nuts.
NOTE: Be EXTRA careful when removing the nuts!!! Unless your sockets are magnetized, I recommend you loosen them just enough with the socket so that you can remove them by hand, as they are small and would be an absolute pain to find if you were to drop one anywhere near the engine block (been there, done that).
2. Once all bolts and nuts are removed, gently lift the manifold off the engine block. Place it near the manifold gasket along with the bolts and nuts.
TIP: To prevent debris from falling into the engine block, cover the center of the block (cylinder openings) with one of the clean shop rags.

 

From what i remember just make sure all the bolts are undone then pull up. Might be a little bit difficult the first time if it hasnt been removed before. But whenever i have its easy...and to clarify were talking about the lower plenum right?

 

yes the lower plenum, manifold.
its weird, i removed all the bolts, around 8 of them, and harnesses that could be connected to manifold. but its like stuck there.

 

should the gasket be replaced when i do get it opened?

 

go find a repair manual on line or at any auto parts store.

mine was a pain the first time i took it off use a rubber amllet and lightly tap to break it free. if you have all the bolts un done that is

 

it was little stuck. i got it off. thanks

 

Yes all gaskets should be replaced

 

umm..because i have the motordyne spacer on, i also have the motordyne manifold gasket. does this need to be replaced?
