Make sure to use an airgun or brake clean and spray down the outside edges of the valve cover so when you break it loose no dirt falls into the motor. May be overkill but i am a neat freak when working on motors. Oh and dont use lint rags to clean. I think you could buy some lint free cloths from autozone or equivelent.
theres 2 VC gaskets that you need, the inner and outer.
-remove IC pipes
-unbolt the TB and move it aside
-take off valve cover
-scrape off any silicone from around the cam humps
-install new gaskets
-put a dab of silicone at each corner of the cam humps
-install everything back
