Product Details

The Cometic C5840-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Ford FE V8 engines. This precision-manufactured gasket features a .040" compressed thickness and accommodates a 4.400" bore diameter, making it ideal for performance builds and engine rebuilds requiring enhanced sealing capability.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability under high compression and boost
  • .040" compressed thickness allows for precise deck height and compression ratio tuning
  • 4.400" bore diameter designed for standard and mildly overbored FE engines
  • Advanced coating technology provides excellent micro-sealing properties
  • Resists blow-out and maintains consistent clamping force through heat cycles
  • Does not fit 427 SOHC (Cammer) applications

Cometic's MLS gaskets utilize multiple layers of stainless steel with proprietary coatings to create a gasket that conforms to surface imperfections while maintaining structural integrity. This design is particularly effective in high-performance applications where cylinder pressure and temperature extremes demand maximum reliability. Compatible with Ford FE engine families including 352, 360, 390, 406, 410, 427, and 428 cubic inch variants (excluding 427 SOHC).

I love simple, easy and fast, and ordering from you met this criteria. Thank you!

Great pricing!! cheapest products on the web!

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

Web site has a lot of items without much description.

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

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
