Product Details

The Cometic C5406-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. This precision gasket features a .040" compressed thickness and is designed to accommodate a 4.135" bore diameter, making it ideal for performance builds and applications using Brodix BD2000 cylinder heads.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .040" (1.02mm) compressed gasket thickness
  • 4.135" bore diameter for optimal combustion chamber sealing
  • Specifically designed for use with Brodix BD2000 cylinder heads
  • Compatible with Chevrolet Gen-1 Small Block V8 engines
  • Exceeds OEM standards for high-performance and racing applications

Cometic MLS head gaskets utilize multiple layers of stainless steel with a Viton rubber coating to provide maximum sealing capability under extreme cylinder pressures and temperatures. The embossed sealing beads around combustion chambers, coolant passages, and oil return holes ensure reliable sealing even in boosted or high-compression applications. This gasket is an excellent choice for engine builders seeking precision fitment and long-term reliability in performance and racing environments.

Found item i was looking for at a better price than any other website! Fast shipping and great custumer service. will be buying from them again. Thanks!

The site was easy to use and I'm currently awaiting my items. So far the ease with shopping using autoplicity was what I expect of a web site - extremely easy and user friendly. Way to go guys and keep up the great work!

Very fast transaction and shipping info.. Best price found on the internet..

Had the hard to find part I was looking for in stock. Ordered it late saturday night, first thing monday morning it was shipped out! Couldnt of asked for more!

Lightning fast service! Good prices.

I needed a few small XRP fittings for our NHRA Top Alcohol Dragster, I had called XRP and even a "pro racer discount" the price was ridiculous; couple this with their ridiculous shipping/handling charge I had to go elsewhere. I typed in the XRP part number into Google and found Autoplicity, twice as many pcs. as I was planning on ordering and with shipping it was cheaper than one fitting from XRP direct. I will be checking Autoplicity anytime I'm ordering something from this day on, everything about the transaction was smooth and simple. I just got my tracking number today and the stuff is on its' way. Thanks for making this transaction so easy and not robbing your customers on something as frivolous as "handling".<br><br>Respectfully,<br>Brandon Booher<br>NHRA TAD #34

Quick and easy! Love the Amazon pay feature!
