Product Details

The Cometic C5411-040 is a premium multi-layer steel (MLS) cylinder head gasket engineered specifically for Chevrolet Generation 1 Small Block V8 engines. This gasket features a compressed thickness of .040 inches and is designed to accommodate a 4.060-inch bore diameter, making it ideal for performance builds and engine rebuilds requiring precise sealing.

Key Features:

  • Multi-layer steel (MLS) construction provides superior strength and durability under high-pressure and high-temperature conditions
  • 4.060-inch bore size accommodates stock and slightly overbored small block Chevy engines
  • .040-inch compressed thickness allows for precise compression ratio tuning
  • Valve pocketed bore design prevents valve-to-gasket interference in performance applications
  • Compatible with Vortec cylinder heads for improved sealing and performance
  • Designed to withstand extreme cylinder pressures in naturally aspirated and forced induction applications

Cometic's MLS gaskets utilize multiple layers of stainless steel with elastomeric coatings to create a superior seal that adapts to minor surface imperfections. This design makes the C5411-040 an excellent choice for street performance, racing, and high-output small block Chevrolet builds where reliability and consistent head sealing are critical.

These people are just awesome! I got my Thule Bike Rack for a fraction of the cost compared to everywhere else. Shipping was very fast and cheap but when I received it there were a couple of missing hardware parts. Thule wanted to make me ship the whole thing back. Rob Fratu of Autoplicity took control of the situation and got Thule to ship me the missing parts and some extras, all within a couple of days. I cant remember a better experience with a retailer.

Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

They had what I needed, No hassle ordering. and it shipped fast.

Very easy mobile site!

Easy to use web site. Quickly found what I needed. Smooth check out and SUPER FAST delivery. Couldn't ask for a better transaction experience. Bookmarked and for sure "GO TO" for next auto parts search. Thanks Autoplicity

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!

Great store! Best prices, fast fedex shipping. Very satisfied, will buy from Autoplicity again!

Placed my order for my K&N CAI on saturday, but didnt have enough cash so the order finalized on sunday morning. Autoplicity provided excellent service via phone and I should be receiving my CAI later today!!!! Super Stoked. Thank you Autoplicity for providing good service!!<br>Will buy from this site again!!

Wow super fast shipping and I ordered over a holiday weekend. Will be doing business with this site again soon.
