Product Details

The Cometic C5755-074 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Big Block V8 engines. This gasket features a .074" compressed thickness and is designed for a 4.400" bore diameter, making it ideal for performance builds and engine rebuilds requiring precise sealing.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .074" compressed thickness provides optimal compression and sealing
  • 4.400" bore diameter designed for Buick Big Block V8 applications
  • Excellent resistance to extreme temperatures and pressures
  • Engineered to handle high-performance and racing applications
  • Prevents combustion leaks and maintains consistent compression

Cometic MLS gaskets utilize multiple layers of stainless steel with specialized coatings to provide maximum sealing under extreme conditions. The embossed layers create a micro-seal around the combustion chamber, coolant passages, and oil ports, ensuring reliable performance in both street and race applications.

If you could give a much better tracking information, I'd give 5 stars. You're tracking only stated my order was placed, and received. I had a heavy order. My help was not going to be around more than a week. So I was nervous as heck! The stress of the unknown gave me a headache and made me feel I needed to cancel the order and get one locally that week. But after a lot of praying God came through and I was so happy to receive it on Tuesday after only 4 business days. It was a great price. It seems to work okay on the first day, and I hope it lasts a while. Thank you!

Pricing was good, product was available, and shipping was pretty darn good too!!

Gotta wait awhile, hope it’s perfect when it arrives so I don’t have to return it.

Part arrived quickly but still haven't installed it.
