Product Details

The Cometic C5454-070 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler Gen-2 Hemi engines. This high-performance gasket features a 4.280-inch bore diameter and .070-inch (70 thousandths) compressed thickness, making it ideal for stroker builds and applications requiring increased compression or deck clearance.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • 4.280" bore diameter accommodates stroker and overbored Hemi applications
  • .070" compressed thickness allows for precise compression ratio tuning and deck height adjustments
  • Designed specifically for Chrysler Gen-2 Hemi engines (5.7L, 6.1L, 6.4L applications)
  • Advanced embossment technology ensures excellent sealing around combustion chambers and fluid passages
  • Viton rubber sealing beads provide optimal oil and coolant containment

Cometic MLS head gaskets feature multiple layers of stainless steel with an advanced coating system that promotes proper sealing and release characteristics. The gasket's design allows it to recover and maintain seal integrity through extreme thermal cycles, making it an excellent choice for high-performance street engines, forced induction applications, and racing builds. Sold individually—two required per engine.

Great pricing!! cheapest products on the web!

Your competitive pricing won my business through the internet and I wasn't disappointed. The price was great ( about 1/2 MSRP) and item was shipped very quickly. No backorder problems here! I was impressed with the quality of my H pipe and with the packaging.

I really like how prompt the order went through and the quality of the part im getting

Great place to shop online. The best price on the internet and super fast delivery. Shop with Autoplicity, highly recommended.

Autoplicity leads the way ! Others take a lesson !! Great prices and excellent service !!!

Autoplicity had the best price for my Thule 867 roof rack cargo bag. It was easy to pay thru my Amazon accont and the order shipped within 24 hours of my placing the order.

Fast shipping and good prices. I would shop this site again.
