Product Details

The Cometic C5478-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford 302 and 351W Windsor V8 engines with SVO heads. This gasket features a 4.030-inch bore diameter and a compressed thickness of .040 inches, making it ideal for performance builds and high-compression applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme cylinder pressures
  • .040-inch compressed thickness allows for precise compression ratio tuning
  • 4.030-inch bore diameter optimized for SVO cylinder heads
  • Embossed stainless steel outer layers with viton rubber coating for maximum conformability
  • Designed to withstand high heat and extreme cylinder pressures in performance applications
  • No re-torque required after initial installation

Cometic MLS gaskets are the preferred choice for engine builders and performance enthusiasts who demand reliable sealing in boosted, nitrous, or high-compression engines. The multi-layer design allows the gasket to recover while maintaining vehicle seal integrity, making it perfect for both street and track applications.

They had the lowest price by far! Quick shipment! I am going back for more. Thanks!<br><br>Order 6489

able to process order very quickly

Your competitive pricing won my business through the internet and I wasn't disappointed. The price was great ( about 1/2 MSRP) and item was shipped very quickly. No backorder problems here! I was impressed with the quality of my H pipe and with the packaging.

I really like how prompt the order went through and the quality of the part im getting

Even though I checked the 20offshipping it did not apply it at checkout.

Great place to shop online. The best price on the internet and super fast delivery. Shop with Autoplicity, highly recommended.

Autoplicity leads the way ! Others take a lesson !! Great prices and excellent service !!!

Autoplicity had the best price for my Thule 867 roof rack cargo bag. It was easy to pay thru my Amazon accont and the order shipped within 24 hours of my placing the order.

I only gave them a 3 star raring on their shipping because I went on their site on Tuesday and the order said it had not been shipped. On Wednesday I received my shipment. The left hand needs to figure out what the right hand is doing. Other than that, GREAT
