Product Details

The Cometic C5329-092 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Mark IV Big Block V8 engines with a 4.375-inch bore diameter. This precision gasket features a .092-inch compressed thickness, providing exceptional sealing performance for both stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction with multiple layers of stainless steel for superior strength and durability
  • 4.375-inch bore diameter designed for Chevrolet Mark IV Big Block V8 engines
  • .092-inch compressed thickness for optimal compression ratio tuning
  • Viton rubber sealing beads around critical sealing areas including combustion chambers and fluid passages
  • Embossed stainless steel layers provide even clamping load distribution
  • Reusable design allows for multiple installations when properly handled
  • Compatible with aftermarket performance cylinder heads and engine builds

Cometic MLS head gaskets are a preferred choice for engine builders and performance enthusiasts due to their ability to withstand extreme cylinder pressures, high temperatures, and engine movement.

The order was placed on a weekend (Order #30758 <br>Order Date: Saturday, September 15, 2012 Order Total: $31.73 <br>It was processed on the first business day. I couldn't ask for a quicker response.<br><br>Good joob all !!!<br>Marty Spellman

Fast shipping, product was excellent .

Very friendly customer service! They also shipped my radiator out very quickly. I will definetly be ordering from autoplicity again!

Amazing !! FAST SHIPPING and GREAT PRICES !! I couldn't ask for better !! I will definitely shop with Autoplicity again !!

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
