Product Details

The Cometic C5753-027 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Big Block V8 engines with a 4.312-inch bore diameter. This precision-manufactured gasket features a compressed thickness of .027 inches, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.312-inch bore diameter designed for Buick Big Block V8 applications
  • .027-inch compressed gasket thickness
  • Engineered to withstand extreme cylinder pressures and temperatures
  • Provides excellent resistance to combustion gas leakage
  • Accommodates minor surface imperfections for reliable sealing

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a gasket that conforms to sealing surfaces while maintaining structural integrity under high-performance conditions. This design is ideal for both stock rebuilds and high-performance applications where cylinder head sealing is critical.

I am very pleased with the quickness my product was shipped. I have had problems with other products i have ordered once again Thank You.

Good so far

I went through the Amazon payment option and it was a hassle.

Only place I found that had the product I needed. Extremely satisfied!

this is a great deal on a set of bedrail caps

Will use Autoplicity in the future. Just dont fully belive the 24hour shipping. I ordered 2 parts that where listed as in stock and it still took 3 days to ship. When I called customer service about my order agents where rude and stated there shipping is based upon 24 "buisness" hours.

Quick Shipping and friendly Service

Great prices, availability

quick & easy

I placed the order on Monday, and the package was delivered two days later, on Wednesday...and that was with FREE SHIPPING!!! It was also at the best price I could find. What more can you ask?

Very easy and great price.

Ordered some fluid coolers for a project, great price, easy website, FAST shipping!

tried to order a gasket with my exhaust pipe, shipping jumped12 just for gasket!! Not happening!!
