{"product_id":"mr-gasket-ultra-seal-header-gaskets-5917","title":"Mr. Gasket Ultra-Seal Header Gaskets - 5917","description":"Manufactured from high-temperature steel core\/graphite faced exhaust material. Expanded steel core provides stability and maximum torque retention to eliminate gasket failure. Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head. Conforms to and seals minor surface irregularities. High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load. Can be trimmed if necessary for modified port applications. For original equipment replacement, high performance street, drag race and oval track use.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufactured from high-temperature steel core\/graphite faced exhaust material\u003c\/li\u003e\n\u003cli\u003eExpanded steel core provides stability and maximum torque retention to eliminate gasket failure\u003c\/li\u003e\n\u003cli\u003eGraphite impregnated facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head\u003c\/li\u003e\n\u003cli\u003eConforms to and seals minor surface irregularities\u003c\/li\u003e\n\u003cli\u003eCan be trimmed if necessary for modified port applications\u003c\/li\u003e\n\u003cli\u003eFor OE replacement, high performance street, drag race and oval track use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e Fits 1955-1991 Chevrolet 262-400 Gen I Small Block.
