Going to remove injectors and need to remove the upper intake manifold.

Looking at gaskets and see two types. A flat one piece fiber or three double o-ring style that go in separately in pairs.

I'd prefer the o-ring style as they are Fel-Pro but I'm not sure how they stay in position as the intake is re-installed. Is there a groove in the lower manifold or upper manifold to hold them?

Thanks

The plastic upper intake (1995+) uses the rubber oring style, the aluminum (Pre 1995)uppers use the flat phenolic/paper style.

The oring style fit inside of grooves in the plastic, you will need to remove the old ones with a small screw driver or pick...they will be hard as a rock and come out in pieces.

EDIT:.......I was thinking 4.0...but the 3.0 is the same concept I believe.

Yeah, this is correct, but with a minor change to the years. The aluminum upper intake manifold was used through late 2000/ early 2001. After that, it was the plastic upper.
