the gaskets 4 mine were like 50 bucks, its an improved design, better that oem. since i have a gtp, i had 2 remove the fuel rails, supercharger and the the lim, and what ever other little stuff that was in the way. since yours is just a gt it mite be easier. get a haynes manual from auto parts store, comes in handy. since it was the 1st time i ever did anything like that it took me like 3-4 hrs to take everything apart. like 1.5 hrs to put it back 2gether.
