I have a 454 in a 70 Camaro, Headman ceramic headers, and an aggravating "tat tat tat" leak on #5 that I can't tighten out of. It appears to have a multi layer aluminum gasket now. Which brand is the hot ticket now? Not concerned with re-use etc, just want a quality gasket to get rid of that leak. Saw some made by MAHLE, Mr. Gasket, Remflex..... more names than I ever knew made them.
