About this product

Part #: C5646-027

Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.027". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

What made you choose this particular product?
Again, pretty much all builds lead to using Cometic gaskets in boosted applications. As a measure of safety, I thought it worth the price to go with it as well.
Is this your first time buying from this brand? Did you consider other brands?
I have a spare FelPro OEM spec gasket but...I'm not going to lie, the cache of having an upgraded part squeezed between the block and the head is enough.
Was it easy to install? Any installation tips that will help others?
Super easy if you've already got the head off the car.
