Product Details

The Cometic C5691-075 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Stage I and Stage II V6 engines. This precision-manufactured gasket features a .075" compressed thickness and a 3.860" bore diameter, making it ideal for performance builds and engine rebuilds requiring reliable sealing under elevated compression and cylinder pressures.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .075" (0.075 inch) compressed gasket thickness
  • 3.860" bore diameter designed for Buick Stage I and Stage II V6 engines
  • Engineered to withstand high combustion pressures and temperatures
  • Provides excellent resistance to gasket failure and blowout
  • Precision-cut for accurate fitment and consistent sealing

Cometic's MLS gaskets utilize multiple layers of stainless steel with a Viton rubber coating, providing exceptional conformability to sealing surfaces while maintaining structural integrity. This design allows the gasket to recover and maintain seal integrity through thermal cycling and engine movement, making it an excellent choice for performance and racing applications.

Need to have actual photos of items and descriptions.

I was supposed to get a coupon giving me 30% off shipping on this order but it did not apply. Can you check this out and issue the credit?

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere

I ordered new leaf springs for my Jeep Cherokee. Its already headed out to me. Ordering was nice and easy. I'll post more once i get it.

Quick, easy, and strait to the point. Thank you, Chadd

Wanted to pay with PayPal but could not get the link to work... Also asked to combine 2 orders in to 1 and was told it was not possible...
