This high-performance gasket features a compressed thickness of .066 inches (66 thousandths), making it ideal for performance applications requiring precise deck height and compression ratio tuning.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • 4.375-inch bore diameter designed for Chevrolet Mark IV Big Block V8 engines
  • .066-inch compressed thickness allows for compression ratio adjustments and deck height optimization

Cometic MLS gaskets are the preferred choice for engine builders and performance enthusiasts who demand reliable sealing in high-horsepower applications. The multi-layer design allows the gasket to conform to slight surface imperfections while maintaining superior combustion sealing. Proper surface preparation with recommended RA finish specifications is essential for optimal performance.

So far so good

Great experience with autoplicity. Fast shipping. Ordered on 5/31 got bed cover on 6/2. Fit truck perfect.

I was skeptical about Autoplicity since I hadn't heard of them before, and that their price was 12% lower than anyplace else I could find. Plus, I couldn't even find a store around here that carried the X-jack. Plus I got it delivered right This my door fast. You people are Excellent!

The best price found on the net for an Airtex fuel pump. Fast shipping via UPS. Received 08/09/2012<br><br>Autoplicity is now in my favorites. Order Number: <br>Ray J.

Excellent business and a pleasure to deal with. Lowest prices on the net and great communication between the business and myself. Will purchase from again!

Shopping was quick and fast now just waiting on order Got order and can't wait to install

the shipping charges were high, but still cheaper than any place else with free shipping!

Very easy to order, updated regularly on status, great pricing and product
