I have RTV only around the valve cover and used the RTV to form o-rings. It's only a temporary solution and i think my car had RTV only to begin with since there was no gasket on the cover or any o-rings, plus the bolts were tightened all the way when i first began working on this. I thought this was strange. I also didn't use the plugs since I didn't want to use some of the gasket kit and not all of it (hence a slightly cracked valve cover). I knew the 91-92 headers were better than any other saturn headers; i saw one on ebay about a month ago and was gonna bid on it but got lazy and haven't seen any since (dammit). OBX is my other option but I think you have to do some fabrication to make it fit which i don't wanna put up with.
