ROL Gaskets offer high temperature gaskets for Chrysler 361, 383, 400, 413, 426 (except Hemi) and 440 engines, that are built layer by layer to offer the highest level of heat resistance and torque retention available. The ROL HG31130HT High Temperature Head Gasket is ideal for high compression street performance and race applications. Starting with a rugged steel core, the gaskets combine facing layers of high temperature flexible graphite with stainless steel fire rings, topped with silicone coating and Pozi-Seal beading. Graphite is superior to other body materials in its heat resistance and transfers heat laterally through the entire gasket, eliminating hot spots. Also, stainless steel fire rings withstand 200 degrees higher combustion than conventional combustion armor. Contact: ROL Manufacturing Canada Ltd., 4480 Chesswood Dr., Toronto, ON M3J 2B9.
