Need advise on (hopefully not most expensive) recommended brands (or specific set) for Intake Manifold Gasket for V6 3800, Regal LS 97, L36 if my memory is good).

By intake manifold I mean large black plastic that is connected to throttle body on the very top of engine.

Don't need it to be good for many years, 3 years is plenty. Basically just not defective out of the box.

What should I look for in the gasket set, that is easy to replace once intake manifold removed?

Are there O-rings or other gasket/rubber parts right under/inside intake manifold that may need replacement?
Won't remove whatever engine part is below intake manifold.

My goal is to reduce vacuum leaks.

Any unusual tools/oils/etc needed for this job? (I have 1 car and auto shop is very far)
