Product Details

The Cometic C5636-040 is a premium multi-layer steel (MLS) cylinder head gasket engineered for GM and Mercury Marine big block V8 Gen-IV, Gen-V, and Gen-VI engines. This high-performance gasket features a .040" compressed thickness and is designed for engines with a 4.580" bore diameter.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability under high combustion pressures
  • .040" compressed thickness allows for precise deck height and compression ratio tuning
  • 4.580" bore diameter accommodates stock and slightly overbored big block applications
  • Designed for GM/Mercury Marine Gen-IV, Gen-V, and Gen-VI big block V8 engines
  • Configured with 4 bolt holes in the lifter valley area for proper engine architecture
  • Precision-manufactured to OEM specifications for reliable sealing

Cometic's MLS gaskets feature multiple layers of stainless steel with specialized coatings that allow the gasket to recover and maintain sealing integrity even under extreme thermal cycling. The embossed layers provide additional sealing force around combustion chambers, coolant passages, and oil galleries. Ideal for performance builds, engine rebuilds, and marine applications requiring maximum reliability.

Best prices, Super fast shipping!

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

Autoplicity had the products I was looking for at a great price. Their site made for an easy transaction. Their customer service on the phone was helpful as well. Can't wait to get the parts incstalled on my truck.

After weeks of shopping around, I was able to find the best price from Autoplicity. The ordering process was very simple since I had the option to pay through my Amazon account. Great experience.

These guys have the best prices available online. There customer service is on point as well.
