Product Details

The Cometic C5754-098 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Big Block V8 engines. This high-performance gasket features a 4.385-inch bore diameter and a compressed thickness of .098 inches, providing an excellent balance of sealing capability and compression ratio control.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.385-inch bore diameter designed for Buick Big Block V8 applications
  • .098-inch compressed thickness for precise compression ratio tuning
  • Advanced coating technology ensures optimal sealing under extreme pressures and temperatures
  • Accommodates thermal expansion and engine movement better than traditional composite gaskets
  • Ideal for performance builds, forced induction applications, and high-compression engines

Cometic MLS gaskets are manufactured using multiple layers of stainless steel with proprietary coatings, making them the preferred choice for engine builders and racers who demand maximum reliability. The gasket's ability to withstand extreme cylinder pressures and temperatures makes it particularly well-suited for performance and racing applications where traditional gaskets would fail.

GREAT PRICES AND COMMUNICATION!!!! HIGHLY RECOMMENDED STAFF AND PRODUCTS!!!!!

Great price on my Rampage rear bumper, good customer service, bit of a wait on the processing, but not horrible. After its all said and done, I'd shop here again.

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

absolutely lowest price on my Griffin radiator and super fast with the shipping to boot, what more could you ask for!

Thanks again! Best prices I found on the web! Fast shipping Would definitely buy from again!

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!
