Description

The DNJ Engine Components HGB3103 is a professional-grade head gasket set engineered for comprehensive top-end engine service or cylinder head replacement. This kit provides critical sealing between the cylinder head and engine block, essential for maintaining combustion pressure and preventing leaks of oil, coolant, and gases. The set is manufactured using Multi-Layer Steel (MLS), graphite, non-asbestos composite materials, rubber, silicone, and EPDM, with premium Viton® valve stem seals for excellent heat and oil resistance, meeting or exceeding OEM quality standards. Included in this complete set are head gaskets, upper and lower intake manifold gaskets, plenum gaskets, exhaust manifold gaskets, valve cover gaskets and grommets, valve stem seals, camshaft seals, spark plug tube seals (when applicable), thermostat gaskets, a wide assortment of O-rings and seals, and Head Bolts. It is crucial to use new Torque-To-Yield (TTY) head bolts, as reusing them can compromise clamping force and lead to engine failure. DNJ Engine Components offers a large inventory of MLS head gasket sets for wide vehicle coverage. This DNJ® Head Gasket Set with Head Bolts is designed for 1987-1996 Chevrolet and GMC vehicles equipped with the 5.7L V8 OHV Naturally Aspirated engine. Specific fitment details include applications for Chevrolet Blazer, Camaro, Caprice, G10, G20, Tahoe, and related AM General, Buick, and Cadillac models within the specified year and engine range. The product comes with a 12-month or 12,000-mile warranty, whichever comes first.
