Product Details

The Cometic C5245-027 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for first-generation Chevrolet Small Block V8 engines. This precision-manufactured gasket features a .027" compressed thickness and is designed to accommodate a 4.060" bore diameter, making it ideal for performance rebuilds and mild street/strip applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high cylinder pressures
  • .027" compressed gasket thickness for precise compression ratio tuning
  • 4.060" bore diameter accommodates stock and slightly overbored small block Chevy engines
  • Compatible with 18-degree and 23-degree cylinder head configurations
  • Round bore design for optimal combustion chamber sealing
  • Embossed stainless steel layers with elastomeric coating resist blowout and provide maximum recovery
  • Reusable design allows for multiple installations when properly handled

Cometic MLS gaskets are the preferred choice of engine builders and performance enthusiasts who demand reliable sealing in high-performance applications. The advanced MLS technology accommodates minor surface imperfections while maintaining excellent combustion sealing, making this gasket suitable for both naturally aspirated and forced induction builds up to moderate boost levels.

Best price, and shipped fast.

Good Service!

I like it so much it was easy to do I will be ordering some other things for my truck through u guys and the delivery time was great it did not take long at all to get it that is a high and a great thing for me thank u so much

I needed a power steering cooler and I found what I think will work. The price was good but shipping was high.

I placed my order with ease. The product was delivered free of charge within a week. I am very pleased with all the services provided to make my purchase and delivery easy and expeditious.

Good service.

Had the product I needed at a price that couldn't be beat. The shipping was a little high, but not completely out of line, either, and it was still better than other companies who have even MORE ridiculous shipping rates. Will buy from them in the future if they have what I need.

Great price and fast shipping!

quick and easy

Great prices and easy transaction

Best price I could find on line, shipped really fast. With how low the price is I was worried but everything came fast and it was the correct parts. This place really keeps the cost of racing down.

Everything went seamlessly. I placed my order on a Thursday and it got here Tuesday morning. No problems, and it was the best price I could find.

using amazon pay is easy I was not able to track the UPS shipment until the day of delivery. Maybe the number did not scan correctly at the time of shipment. Customer service did show it was shipped on time, and it arrived quickly.
