I made my last gaskets out of laminated aluminum from McMaster. It's .002" aluminum layed to .048". I cut a piece (6"x6" + -)and laid it on the side pipe flange. I use an awl to mark the out side and a transfer punch to mark the holes. Cut and drill. I also have tried the red hi-temp silicon with some success. I did use the hi-temp silicon with the new gaskets. Over 2000 miles and no leaks. I have tried Mr Gasket gasket, industrial gasket and several other gaskets. Most I blew out with in hours. The red hi-temp silicon last several months. I can sell you 2 pieces from the sheet that I bought. Cost about $4 each. Tell me the size you need if your interested in making your own.
