{"title":"Cylinder Heads \u0026 Gaskets","description":"\u003cdiv class=\"collection-description\"\u003e\n\u003ch2\u003eCylinder Head Gaskets \u0026amp; Engine Sealing — Complete Gasket Solutions\u003c\/h2\u003e\n\u003cp\u003eA comprehensive gasket and sealing program is one of those unsexy but absolutely critical aspects of any engine build or rebuild. The finest pistons, crankshaft, and camshaft combination in the world will be undermined by a compromised head gasket, a weeping valve cover, or a leaking intake manifold seal. Getting sealing right from the start — using quality gaskets manufactured to the correct dimensions and from materials appropriate to your application — is the foundation of an engine that runs cleanly, stays together long-term, and makes the power it should.\u003c\/p\u003e\n\u003cp\u003eBilly's Speed Shop stocks over 240 gasket and sealing products from trusted names including Cometic, SCE, and Mr. Gasket — covering everything from critical head gaskets for high-performance applications to complete engine overhaul gasket sets, valve cover gaskets, and speciality sealing solutions for modified combinations.\u003c\/p\u003e\n\u003ch3\u003eHead Gaskets — The Most Critical Seal in Your Engine\u003c\/h3\u003e\n\u003cp\u003eThe cylinder head gasket operates in the most demanding environment of any engine seal — sealing combustion pressure that can exceed 1,000 psi in performance applications, managing enormous temperature differentials between the combustion chamber and coolant passages, and doing so cycle after cycle for hundreds of thousands of repetitions. Choosing the right head gasket for your application is not the place to economise.\u003c\/p\u003e\n\u003cp\u003eFor standard and mild performance applications, premium OEM-style multi-layer steel head gaskets provide reliable sealing at correct torque specifications without the need for speciality preparation. For high-performance builds — particularly those running significant boost, high compression, or nitrous — multi-layer steel (MLS) gaskets from specialists like Cometic offer enhanced sealing capability and the ability to be ordered in specific thicknesses to dial in compression ratio. MLS gaskets require a smooth, properly prepared sealing surface and are the professional choice for any serious engine build.\u003c\/p\u003e\n\u003ch3\u003eComplete Engine Gasket Sets\u003c\/h3\u003e\n\u003cp\u003eA complete engine gasket set covers every sealing surface in the engine in a single convenient package — ideal for engine overhauls, rebuilds, and fresh engine builds where you want to replace every seal and gasket at once rather than hunting individual components. Our gasket sets cover the major American V8 families and include all critical seals: head gaskets, intake manifold gaskets, exhaust manifold gaskets, valve cover gaskets, oil pan gaskets, water pump gaskets, and the dozens of smaller seals and O-rings that complete the package.\u003c\/p\u003e\n\u003ch3\u003eIntake Manifold, Valve Cover, and Oil Pan Gaskets\u003c\/h3\u003e\n\u003cp\u003eIndividual gasket sets for specific applications allow targeted replacement when only particular sealing surfaces need attention. Valve cover gaskets are a common maintenance item as engines age, particularly on vehicles that have seen temperature cycling and the natural hardening that affects rubber-based sealing materials over time. Our valve cover gasket range covers both OEM-specification replacement and improved aftermarket designs that provide better sealing performance than the original components.\u003c\/p\u003e\n\u003cp\u003eIntake manifold gaskets are critical sealing components that influence not just oil and coolant sealing but also the air-fuel charge entering the engine. A compromised intake manifold gasket can cause lean conditions, vacuum leaks, and in liquid-cooled intake applications, the potential for coolant ingestion — making quality gasket selection here particularly important.\u003c\/p\u003e\n\u003ch3\u003eTiming Cover, Water Pump, and Speciality Gaskets\u003c\/h3\u003e\n\u003cp\u003eThe engine's front cover, water pump, and timing components all require quality sealing materials appropriate to their specific operating conditions. Our range extends to timing cover gaskets and seals, water pump gaskets, and throttle body gaskets for EFI applications — ensuring you can source every sealing component for your build in one place.\u003c\/p\u003e\n\u003ch3\u003eGasket Making Material and RTV Sealing Products\u003c\/h3\u003e\n\u003cp\u003eFor custom applications, one-off fabrications, or situations where a pre-made gasket isn't available for your specific combination, gasket making material allows the fabrication of precisely fitted gaskets from sheet stock. Combined with quality RTV silicone products for corner seals and supplementary sealing on specific applications, these materials give the experienced engine builder complete flexibility in their sealing approach.\u003c\/p\u003e\n\u003c\/div\u003e","products":[{"product_id":"1121g","title":"Mr. Gasket Head Gasket - Graphite and Steel","description":"\u003cdiv class=\"billy_features_content\"\u003e\n  \u003ch3\u003eOverview\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cp\u003eGraphite \u0026amp; steel construction, proprietary polymer coated. 4.140 inch Gasket Bore, .028 inch Compressed Thickness.\u003c\/p\u003e\n    \u003cp class=\"mt-2\"\u003eFits 1967-1992 Chrysler 318\/340\/360 LA Small Block. 4.140 Inch Bore, .028 Inch Compressed Thickness\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Mr. Gasket","offers":[{"title":"Default Title","offer_id":50564415127846,"sku":"1121g","price":39.16,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1666\/1542\/files\/5c3d02125f28c4ed89bb9ea095047ee16ceed4de_01106e44-5644-4548-b022-57f70e07627e.jpg?v=1757066447"},{"product_id":"1130g","title":"Mr. Gasket Steel Shim Head Gasket","description":"\u003cdiv class=\"billy_features_content\"\u003e\n  \u003ch3\u003eOverview\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cp\u003eMr. Gasket Steel Shim Cylinder Head Gaskets are for high performance street machines, drag racing and oval track racing.

This all results in superior surface contact between block and cylinder head. All head gasket layers\/spacers go through an additional process to significantly reduce forming induced stress. Advantages are reduced brittleness in material, increased flexibility and deformation retention. This stabilizes the gasket, resulting in reduced cylinder bore distortion and improved combustion seal fro the extreme cylinder pressures found in high compression, supercharged and turbocharged applications. A proprietary polymer coating ensures the micro-seal of engine coolant and oil fluids. | A typical MLS head gasket requires a smoother (30Ra) surface finish than composite head gaskets. Mr. Gasket's proprietary polymer coating will seal a surface finish twice as rough (60Ra) as a typical MLS head gasket. For high performance street, drag race and oval track use.
