Product Details

The Cometic Gaskets C5666-070 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket specifically engineered for Ford 385 Series big block engines. This precision gasket features a 4.400-inch bore diameter and a compressed thickness of .070 inches, making it ideal for high-compression and forced induction applications.

Key Features:

  • Multi-Layer Steel construction provides superior sealing and durability under extreme cylinder pressures
  • 4.400-inch bore diameter accommodates stroker and overbored engine builds
  • .070-inch compressed thickness allows for custom compression ratio tuning
  • Engineered specifically for Ford 385 Series engines (429, 460)
  • Advanced embossment technology ensures consistent clamp load distribution
  • Stainless steel construction with Viton rubber sealing beads resists blow-out and combustion gas leakage

Cometic MLS gaskets are the preferred choice for performance engine builders who demand reliable sealing in high-horsepower applications. The multi-layer design allows for slight movement between layers, accommodating thermal expansion and engine flex while maintaining a positive seal. Perfect for street performance, racing, and marine applications requiring precision head gasket solutions.

GREAT PRICES AND COMMUNICATION!!!! HIGHLY RECOMMENDED STAFF AND PRODUCTS!!!!!

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

Thanks again! Best prices I found on the web! Fast shipping Would definitely buy from again!

Absolutely the best bargain you'll find! Don't pay retail mark up at the parts store, buy at Autoplicity and know you're saving money.<br>.

Bought an Autometer Ultra lite 2 pyrometer and it looks great. Autoplicity has the best prices on their products and ships their products very quickly. I will definetly buy from them again.

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.
