The next thing i did was prep the valve head for resealing. i cleaned along where the old gasket was on the head, and wiped it down and removed all the oil on the surface. pay particular attention to the corners of the valve head, you'll find old atb sealant crap there. Make sure to get rid off all that stuff.
Also, you need to remove the old gasket from the valve cover. that can easily be done with a small screw driver, and then once you get a little bit to tug on, just pull the whole thing out
Sometimes, though, its not that easy. as this gasket ages, it also solidifies into a hard plastic, which can crumble, or basically be a pain in the ass to remove. Patience, grasshopper. Also a good idea to do it away from the car, so no pieces chip off and get into the rocker arm assemblies and mess stuff up.
make sure when you wipe away all the old stuff off the valve head, to wipe away from the rocker arms, so that crap doesnt go into the head.
