The Mahle HS54204A is a complete cylinder head gasket set engineered for 1994–2003 7.3 Powerstroke diesel engines. Manufactured to strict OEM standards by Mahle Original, this kit delivers the essential sealing components required when re-installing cylinder heads during an engine overhaul, machine shop rebuild, or high-performance head stud installation. The set features OEM-spec graphite cylinder head gaskets engineered with high-strength combustion fire rings, paired with valve stem seals, exhaust manifold gaskets, water neck/thermostat seals, and related top-end sealing components.

Blown head gaskets, pressurized cooling systems pushing coolant from the degas bottle, oil or coolant deck leaks, and loss of combustion compression are what this gasket set solves. High boost levels, heavy towing stress, and aged factory gaskets cause fire ring degradation and deck surface weeping. Replacing cylinder head gaskets with OEM-grade graphite construction ensures durable combustion chamber sealing and proper thermal compliance across cast iron heads and blocks. It is the cylinder head gasket and upper installation set only; cylinder head studs/bolts, valve cover gaskets with integrated injector harnesses, and lower conversion sets are sold separately.

It fits all 1994–2003 7.3 Powerstroke Ford Super Duty trucks, OBS F-Series, Excursions, and E-Series vans.

Ensure both the cylinder head and engine block decks are verified flat, thoroughly deburred, and cleaned completely free of oil, carbon, and solvent residue before positioning the head gaskets. Verify proper gasket orientation over the block alignment dowels prior to dropping the heads into place; installing head gaskets backward will block vital cooling and high-pressure oil ports, resulting in rapid engine failure. Fasteners must be installed and torqued in the factory spiral pattern across multiple progressive steps strictly following the bolt or stud manufacturer's specifications and lubrication guidelines.
