Product Details

The Cometic C5245-040 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chevrolet Gen-1 Small Block V8 engines. This gasket features a .040" compressed thickness and is designed for 4.060" bore applications with 18 or 23 degree cylinder heads.

Key Specifications:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • Compressed thickness: .040 inches
  • Bore size: 4.060 inches (round bore design)
  • Compatible with 18/23 degree cylinder heads
  • Designed for Chevrolet Gen-1 Small Block V8 engines

Advanced MLS Technology:

  • Multiple layers of stainless steel provide exceptional combustion sealing
  • Embossed layers conform to surface imperfections for optimal sealing
  • Superior resistance to blow-out and head lift under high cylinder pressures
  • Eliminates the need for re-torquing after initial installation
  • Excellent for high-performance and forced induction applications

Cometic MLS gaskets are the preferred choice for engine builders and performance enthusiasts who demand maximum reliability. The advanced multi-layer design accommodates thermal expansion and contraction while maintaining consistent clamping pressure across the entire sealing surface. This gasket is ideal for street performance, racing, and high-boost applications where conventional gaskets may fail.

so far so good!

very responsive service . and more important correct part, fit exactly . will be more than happy to refer you .

My shopping experience was above and beyond super. Delivery was incredibly fast, product packed securely, good deal, great product, super service. Thank YOU!!

The customer service rep I was able to speak to very helpful and was able to email me an actual image of the product that I wanted before purchasing instead of the generic image that was being used on the website

So far, so good!

The picture on the product looks different from my order called service and they were very helpful sending it back

It says normally 2 days delivery, let’s hope that is accurate.

Easy Peasy

Great price and fast shipping, very satisfied!

Best price for the item I needed. Very fast shipping and there consumer service was great on the phone.

Very competive prices, even with shipping costs. Looking forward to using Autoplicity again in the near future.

Great experience! I placed my order on Sunday and my programmer arrived on Thursday - with ground shipping. I unpacked the programmer and it functioned exactly as I had hoped. I will definitely consider purchasing from Autoplicity again!
