Planning for new headgaskets on my stock heads and block...what does everyone use? I see autozone sells the Felpro 9441PT gaskets for $30. Also what sealant should be used? Or can I just put them on dry? I think I remember putting headgaskets on my old truck one time dry and had no problems. Or does the high boost require a sealant? Or should I go back with the factory 87' gaskets from GM?
