Cometic 1UZ head gaskets

Cometic UZ Head Gaskets MLS Multi Layer Steel, 1UZ 2UZ or 3UZ

In most cases, we recommend 1.3mm head gaskets on 1UZ/3UZ (1.0mm on 2UZ), and if you are running custom compression aftermarket forged pistons. If you are keeping the stock pistons and looking to lower the compression ratio for more boost, we recommend a thicker head gasket such as 2mm. This is for BOTH head gaskets.

The 1UZ version of the head gaskets is specifically for the non-VVTi engine and does not surround the oil port going to the VVTi solenoids

Please keep in mind some sizes are exclusively made to order nowadays and will have a 1-2+ month wait time. The OEM head gaskets are more readily available.

Cometic Head Gaskets are developed with the performance enthusiast in mind. With so many individual requirements for each engine, Cometic offers a number of options to suit your specific build and needs.

The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, its ability to rebound, and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.

The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.

C4136 and C4137 offer a standard bore size of 92.5mm. C4211 and C4212 offer a standard bore size of 98mm

Please call or email us for an ETA and cost on other bore sizes, and note that they are special order and will take about 2 weeks to ship.
