This gasket features a 4.250-inch bore diameter and a compressed thickness of .027 inches, making it ideal for high-performance street and racing applications.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability under extreme conditions
  • 4.250" bore diameter accommodates standard and slightly overbored cylinders
  • .027" compressed thickness allows for precise compression ratio tuning
  • Embossed stainless steel outer layers with a soft steel inner layer create a reliable seal
  • Resists combustion chamber pressure and maintains integrity at high temperatures
  • Designed for Chrysler B-series (383, 400) and RB-series (413, 426, 440) big block engines

Cometic MLS gaskets are manufactured using advanced computer-controlled technology to ensure consistent quality and performance. The multi-layer design allows the gasket to conform to cylinder head and block surface imperfections while maintaining excellent sealing properties. This gasket is suitable for both naturally aspirated and forced induction applications, making it a versatile choice for engine builders and performance enthusiasts.

Thanks for offering instant $5.00 back on Order Number: 12559 for writing this review. <br>Great prices and fast shipping. I do not have the part yet but it was the best price on a LT1 MSD opti spark anywhere on the net. Great deal!!! And it was still cheaper than Jegs or Summit even with overnight shipping. Will use again if the deals are this good!

Easy to deal with about shipping questions, great prices, and friendly customer service. One of the few places who says "I'll return you call" and actually does. Thanks...

Great price, very helpful tech support,thanks will buy again<br><br> Chris
