I don`t want to glue both sides, running a solid roller, need to remove once in a while to set/check the valves---- I do have a pair of $38 gaskets on it now. I have built heat guards to help keep the heat off of the valve covers and gaskets, #1-2 tubes are very close to the covers w/ raised port heads. It burned the cork, rubber steel reinforced, and every other kind I tried , ones up after a while , hoping these carbon gaskets will hang in there.
