Product Details

The Cometic C5846-036 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Pontiac 400, 428, and 455 cubic inch V8 engines. This high-performance gasket features a 4.380-inch bore diameter and a compressed thickness of .036 inches, making it ideal for stock and mild performance builds requiring reliable sealing.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.380-inch bore diameter accommodates standard and slightly overbored cylinders
  • .036-inch compressed thickness provides proper compression ratio and sealing
  • Designed for Pontiac 400, 428, and 455 V8 engines
  • Eliminates the need for retorquing after initial installation
  • Withstands extreme cylinder pressures and temperature cycling
  • Engineered to prevent blown gaskets in high-stress applications

Cometic's MLS gaskets feature multiple layers of stainless steel with embossed sealing beads that provide even clamping pressure across the entire sealing surface. This design accommodates minor surface imperfections and maintains a positive seal even under extreme conditions. The gasket is compatible with aluminum and cast iron cylinder heads and blocks, making it versatile for various Pontiac V8 builds.

fast shipping just what i ordered

First purchase , hope it all goes as smooth as ordering .

Fast and awesome deals! Ordered an intake system, everywhere else wanted 300+, auto had it for 215! It's a no brainer! <br><br>Note: I only ever do 4/5 ratings... Always room to improove

I placed my order for an Autometer Shift Light and it was shipped the same day. I was provided a FedEx tracking number in the shipping confirmation email. <br><br>Very easy to select what I wanted to buy and the check out process was simple and quick.

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.

this was my first time shopping at Autoplicity and it kind of made me nervous not really knowing anything about their site but i recieved an order confirmation immediatley after ordering and it was shipped extremely fast.
