Product Details

The Cometic C5769-080 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This precision gasket features a 4.200-inch bore diameter and .080-inch compressed thickness, making it ideal for performance builds and engine rebuilds requiring reliable sealing under high compression and temperature conditions.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability
  • .080-inch (2.0mm) compressed gasket thickness for precise compression ratio tuning
  • 4.200-inch bore diameter designed for Pontiac 400, 428, and 455 V8 engines
  • Stainless steel construction with multiple layers for optimal sealing
  • Handles extreme cylinder pressures in high-performance and forced induction applications
  • Embossed active sealing beads provide excellent conformability to deck surfaces
  • Resists fluid migration and combustion gas leakage

Cometic MLS head gaskets are a proven choice for engine builders and enthusiasts seeking maximum reliability in demanding applications. The multi-layer design allows the gasket to adapt to minor surface imperfections while maintaining consistent clamping force across the entire sealing surface. This gasket is suitable for both street and racing applications where performance and durability are critical.

Super fast shipping and great price..

Wow!! I came across Autoplicity while searching for a fuel pump for my Trans-Am. Not only did they have the cheapest price for the part, but they also had extremely reasonable shipping cost. Most websites claim to have free shipping but it seemed the cost of shipping was added to the cost of their part. Then I find out my order was processed and shipped within one business day!! I'll definately be bookmarking Autoplicity's home page!! Thanks!!

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!

The item arrived fast and in good condition. There however seems to be a glitch with the scale the first time we weighed something. After we shut it off and then back on it seemed to be OK.

I ordered a Grant 1103 Steering Wheel, Order Number: 16767. Great prices, quick shipping, good customer service, an all around deal. Thank you.

The part I purchased had the lowest price I could find online anywhere.. Simple transaction and fast shipping.. Ordered on a Monday and delivered by Friday..

Unbeleiveable!!!! Super fast shipping!! Great job!!! Keep up the good work!<br><br>P Savaria

Great Prices and Very Fast Shipping. Will order again in the future. Customer Service was great when I called about a question with my order.

Great prices and fast delivery.
