Mr Gasket — Engine Gaskets, Dress-Up Accessories & Performance Components

Mr Gasket has been supplying the performance aftermarket with engine gaskets, dress-up accessories, and performance components since 1964, building a catalog that covers the essential sealing and finishing needs of domestic V8 builds from the engine bay to the exhaust system. Whether you're sealing a freshly built engine, dressing up a show car motor, or sourcing performance accessories for a street or race application, Mr Gasket has the components to get the job done correctly.

Engine Gaskets & Sealing Products

Mr Gasket produces a comprehensive range of engine gaskets for domestic V8 applications — including intake manifold gaskets, exhaust manifold gaskets, valve cover gaskets, oil pan gaskets, and complete engine gasket sets. Gasket materials are selected for each application's temperature, pressure, and chemical exposure requirements, with multi-layer steel, composite, and rubber-coated designs available depending on the sealing surface and operating conditions.

Intake manifold gaskets are available in standard and performance configurations, with port-matched designs for popular cylinder head and intake manifold combinations. Correct gasket selection is critical for maintaining port alignment and preventing vacuum leaks that affect idle quality and fuel delivery on carbureted and EFI applications alike.

Valve Covers & Engine Dress-Up

Mr Gasket valve covers are available in stamped steel, cast aluminum, and fabricated designs for Small Block and Big Block Chevy, Ford, and Mopar V8 applications. Chrome, polished, and painted finishes provide options for builds ranging from traditional hot rods to modern restomod projects. Breather caps, oil fill caps, and PCV valve grommets are available separately to complete the valve cover installation with the correct accessories for the build's ventilation system.

Engine dress-up accessories include timing covers, water pump covers, distributor caps, and accessory brackets in chrome and polished finishes that elevate the appearance of the engine bay without affecting performance. These finishing details are the difference between a functional engine build and a show-quality presentation under the hood.

Performance Accessories

Mr Gasket produces a range of performance accessories for domestic V8 applications — including carburetor spacers, throttle return spring kits, fuel line fittings, and engine hardware. Carburetor spacers increase plenum volume and improve airflow distribution to the intake ports, with open and four-hole designs available depending on the carburetor and intake manifold combination. Spacer height selection affects the RPM range where the power gain is most pronounced — taller spacers favor top-end power, while shorter spacers improve low-to-mid RPM response.

Common Applications

Mr Gasket products cover Small Block and Big Block Chevy, GM LS, Small Block and Big Block Ford, Ford FE, Chrysler/Mopar V8, and Pontiac applications. Classic muscle car and hot rod platforms are the primary focus, with product coverage for the most popular engine families used in street and race builds across GM, Ford, and Mopar platforms.

Build Quality & Heritage

Mr Gasket has been part of the Holley Performance family for decades, maintaining the product quality and application coverage that made the brand a staple in the performance aftermarket. Gasket materials meet or exceed OEM sealing specifications for each application, and dress-up components are finished to a standard appropriate for show car and high-quality street builds. The brand's 60+ year presence in the performance market reflects consistent product quality across a catalog that covers the essential needs of domestic V8 builders.

Installation Notes

Engine gasket installations require clean, flat sealing surfaces free of old gasket material, corrosion, and machining marks. Use the correct torque sequence and specification for each gasket application — intake manifold and valve cover gaskets in particular require correct torque to seal properly without distorting the gasket or the sealing surface. RTV sealant is required at the four corners of the intake manifold gasket on most small block applications to seal the end rails where the gasket meets the block.
