Sounds like a seperate topic for Performance and Brainstorming, rather than hijack this one. There are advantages and disadvantages, outlandish and more 'moderated' claims.

Are the LIM gaskets too hard for a couple of amateurs to do?

I did mine mostly by myself over a 3 day weekend, and I goofed off A LOT!!!

It can be done with basic hand tools. Just take the time to clean and label everything.

If you get stuck, dont force anything!!!! Wash your hands and log on here. You can search or ask questions... I did and I got it back together..

Yep you can do it. Like bobfather said, cleanliness is key, especially on the gasket surfaces.

Do the valve cover gaskets too.
