Product Details

The Cometic C5666-027 is a Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford 385 Series engines. This precision gasket features a 4.400-inch bore diameter and a compressed thickness of .027 inches, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel construction for superior durability and thermal resistance
  • 4.400-inch bore diameter optimized for Ford 385 Series big block applications
  • .027-inch compressed thickness for precise compression control
  • Provides excellent sealing under high-pressure and high-temperature conditions
  • Manufactured to OEM specifications with enhanced performance characteristics

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to maintain proper seal integrity throughout extreme temperature cycling and combustion pressures. This design accommodates minor surface imperfections while preventing coolant and combustion gas leakage, making it ideal for both stock and performance engine builds.

It was great to find hard get parts from you

Much better than expected. Received OEM part immediately and in good quality. Will definitely use the site again, thanks!

Shipping came when it said it would now I just have to install this new handle

Easy to order and shipping with in a reasonable time.

Great website, great prices, great shipping speed.

Did not install because no torque specs on product. Too difficult to have to do twice because of install failure. Was emergency situation. Had to just risk 1300 mi. Valve damage.

Very Informative

Only complaint was on box should have put fragile because upon delivery looks like someone stomped all over the box I haven't opened box yet because mech won't be available Hopefully part isn't damaged ..

Great prices, fast shipping and kept me informed with several status e-mails. What more could you want.

Not only did they have an great price on my part, and reasonable shipping charges, they shipped it right away.<br>I know I will be checking them for future parts.

Shopped around for a VDO gauge all over the internet incluing ebay, amazon and at least a dozen online retailers. Autoplicity was at least 10% cheaper than anybody else and a good 30% cheaper than most. The outstanding reviews made me more confident in ordering fom them for the first time.

I've had great service, quick shipment and awesome prices from Autoplicity. Definitely would recommend to anyone. I've placed multiple orders with them and everything is great!

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

The prices and selection are best. The cutomer service rep. did a good job in handling all my questions, and placed my order. I will be using Autoplicity for all my auto parts.

Best price I found and VERY fast shipping. Very happy.
