Cometic Gaskets .036" MLS Cylinder Head Gasket for Buick 192, 231, 252ci V6, 3.86" Bore - C5691-036

If you're diving into the world of performance engines, let me tell you about the Cometic MLS (Multi-Layer Steel) Head Gaskets. These bad boys are designed to deliver top-notch sealing for high-output engines, and trust me, you won't need any sealants with these. They’re perfect whether you’re pairing aluminum heads with aluminum blocks or mixing them with cast iron. The way they handle the shearing forces between different materials is impressive—it's like they were built for the job.

What sets these gaskets apart is their construction. Made from multiple layers of stainless steel, they boast incredible strength and flexibility. The outer layers are embossed and coated with Viton, which is a tough flouroelastomer rubber that can handle some serious heat—up to 482°F (or 250°C). This means they’re ready for whatever harsh conditions your engine throws at them. The center layer is uncoated stainless steel, and you can even adjust its thickness to fit your specific needs.

For those of you working on Buick V6 engines—specifically the 192, 231, and 252ci models—this MLS head gasket is a solid choice. It features a 3.86" bore diameter and a compressed thickness of .036". It’s designed to fit both stock and Stage I-II heads, making it versatile for your performance builds.

Key Features:

  • Bore Diameter: 3.860"
  • Cylinder Head Type: Stock and Stage I-II Heads
  • Engine Compatibility: Buick 192, 231, 252ci V6
  • Thickness: .036"

Now, if you’re wondering where this gasket fits, it’s compatible with a whole lineup of vehicles. We’re talking about various Buick models from the Century to the Regal, and even some Cadillacs and Chevrolets. Whether you’re restoring a classic or upgrading your ride, this gasket will keep everything sealed tight.

So if you’re looking for reliability and performance in your engine build, give the Cometic MLS head gasket a shot. It’s built to last and designed for those who take their engines seriously.
