Engine Gasket Kits for All Makes

What This Category Covers

The Gasket Kits collection covers matched gasket sets used for engine rebuilds, head service, and turbo or supercharger installs. Coverage spans domestic HEMI, Ford Modular and Coyote V8 applications through import 2JZGE, RB26DETT, KA24DE, and 4AGE engines, with both full engine kits and top end only kits available depending on the scope of the job.

Categories Included

Top end gasket kits, complete gasket kits without head gasket, MLS head gaskets, exhaust header and manifold gaskets, oil pan gaskets, throttle body gaskets, blower snout gaskets, turbo inlet gaskets, and blow off valve gaskets.

Domestic HEMI and V8 Gasket Kits

Cometic Street Pro top end gasket kits cover the Chrysler Gen-3 HEMI 5.7L and 6.4L Apache platforms with specific bore and MLS head gasket thickness combinations for each engine. Cometic also supplies the AFM blower snout gasket for the 6.2L supercharged Hellcat engine, a wear item that needs periodic replacement on supercharged HEMI builds.

Popular Domestic Gasket Brands

Cometic Gasket (Street Pro top end kits and MLS head gaskets for HEMI and GM small block platforms), BBK (Ford 302 and 351 header gasket sets), and Fleece Performance (upper gasket kits for RAM 6.7L Cummins diesel).

Import Engine Gasket Kits

Cometic Street Pro top end kits support the Toyota 4AGE, Nissan KA24DE, and Ford 4.6L Modular platforms with bore-specific MLS head gaskets, while the complete Toyota 2JZGE gasket kit covers a full teardown minus the head gasket for builders installing a separately sourced or upgraded head gasket. GReddy supplies small exhaust and turbo system gaskets sized for common Japanese performance turbo and exhaust setups.

Popular Import Gasket Brands

Cometic Gasket (Street Pro kits for Toyota, Nissan, and Honda platforms, plus complete 2JZGE kits), GReddy (exhaust gaskets, blow off valve gaskets, and turbo inlet gaskets for RB26DETT and other Japanese turbo platforms).

Diesel Gasket Kits

Fleece Performance offers upper gasket sets both with and without the head gasket for the 6.7L Cummins in RAM trucks, letting builders choose based on whether they are replacing the head gasket or only servicing upper engine components like the intake and exhaust manifolds.

Choosing MLS Head Gaskets for Performance Builds

Multi-layer steel head gaskets from Cometic are the standard choice for boosted or high compression builds where a stock composite gasket cannot survive the cylinder pressure. Bore diameter and compressed thickness must be matched to your specific piston, deck height, and compression ratio target.

How to Choose the Correct Gasket Kit

• Confirm the exact year, make, model, and engine code before ordering (5.7L HEMI, 2JZGE, KA24DE, 4.6L Modular, and so on)
• Match the bore diameter and MLS thickness to your piston and deck height specifications
• Decide whether you need a full engine kit or a top end only kit based on the scope of your rebuild
• Confirm whether the kit includes or excludes the head gasket, since some are sold separately
• Resurface cylinder heads before installing a new head gasket to ensure a proper seal
• Follow the correct head bolt or head stud torque sequence and specification for your engine
• Replace the blower snout gasket on supercharged HEMI applications as a wear item during service
• Order matching intake and exhaust manifold gaskets when performing a full top end rebuild
• Verify throttle body gasket thickness matches your intake manifold flange
• Use a torque plate when boring or honing cylinders for the most accurate final bore dimension

Common Questions

What is the difference between a top end kit and a complete gasket kit?

A top end kit covers the head gasket, intake and exhaust manifold gaskets, valve cover gasket, and related upper engine seals. A complete gasket kit adds the oil pan gasket, timing cover seal, rear main seal, and other lower engine gaskets needed for a full teardown and rebuild.

Do I need to resurface my head before installing a new gasket?

Yes, in almost all cases. A blown head gasket typically causes localized warping or heat damage to the mating surface, and resurfacing ensures a clean, flat surface for the new gasket, especially important with modern MLS gaskets that require very consistent surface finish.

Why do some kits not include the head gasket?

Some builders source a specific MLS head gasket separately to match a custom bore, deck height, or compression target, so manufacturers offer complete kits without the head gasket to avoid forcing a mismatched gasket into the purchase.

What is a blower snout gasket used for?

The blower snout gasket seals the connection between the supercharger snout and the main supercharger body on Hellcat and other supercharged HEMI applications. It is a wear item that should be replaced any time the snout is removed for service or a pulley upgrade.

Can I reuse a head gasket after removing the head?

No. Head gaskets are single-use components that deform to seal the cylinder head and block on first installation. Always install a new head gasket any time the head is removed.

What is the benefit of an MLS head gasket over a composite gasket?

Multi-layer steel gaskets handle higher cylinder pressure and repeated heat cycling better than composite or elastomeric gaskets, making them the standard choice for boosted, high compression, and frequently serviced performance engines.

Do I need new head bolts or studs with a gasket kit?

Torque-to-yield head bolts generally should not be reused and should be replaced with new bolts or upgraded to aftermarket studs like ARP when installing a new head gasket, since stretched bolts lose proper clamping force.

How do I know what bore size gasket kit to order?

Bore size is determined by your cylinder measurement after any boring or honing work, or by your factory or aftermarket piston specification. Cometic and other manufacturers list specific bore diameters for each kit, so measure before ordering.

Are diesel gasket kits different from gasoline engine kits?

Yes. Diesel gasket kits like the Fleece Performance kits for 6.7L Cummins are engineered for the much higher combustion pressures found in diesel engines and use different sealing materials than typical gasoline engine gasket sets.

Can I install a gasket kit myself?

Basic gasket replacement like a valve cover or oil pan gasket is DIY friendly for experienced enthusiasts. A full head gasket job or complete engine rebuild gasket kit installation requires proper torque sequences, resurfacing work, and engine assembly experience, and is often best handled by a qualified engine builder.
