Head Gasket

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

MLS
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.

CFM-20
A perforated steel core with an elastomer surface is ideal for head gaskets allowing heat to be drawn evenly across the gasket surface while providing maximum sealing characteristics when exposed to coolants and oils.

So far so good!

You can tell customer service is important to this company. Not only were the prices lower than other places but they communicate the status of the order and shipping very well. They obviously care what people think. I was suspicious of all the positive comments but decide to try them anyways. Very happy I did and definitely plan on buying from them again.

Price is the lowest price you can get anywhere. Customer service goes the extra mile helping me with my oder. Delivery was fast and products were as advertised. I will definitely order from Autoplicity again.

This company offers profesional service at a very competitive price. The header collectors i ordered were not available at the big speed outlets. The fast shipping was also a plus. I would recomend Autoplicity to anyone who needs parts in a hurry !
