Product Details

The Cometic C5432-027 is a Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet Mark-IV and GM Gen-V/VI Big Block V8 engines. This precision-engineered gasket features a .027" (0.027 inch) compressed thickness and is sized for a 4.310" bore diameter, making it ideal for performance and racing applications where precise compression control is critical.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability under extreme cylinder pressures
  • .027" compressed thickness allows fine-tuning of compression ratios
  • 4.310" bore diameter accommodates standard and slightly oversized pistons
  • Undersized water ports designed for aftermarket cylinder heads, allowing custom port matching and coolant flow optimization
  • Compatible with Chevrolet Mark-IV, GM Gen-V, and Gen-VI Big Block V8 engines
  • Embossed stainless steel construction with multiple layers for maximum conformability

Cometic's MLS gaskets are the preferred choice for high-performance engine builders, offering exceptional blowout resistance and the ability to withstand high heat and pressure cycles. The undersized water ports provide flexibility for engine builders to customize coolant passage sizing to match specific aftermarket cylinder head configurations, ensuring optimal cooling performance in modified engines.

Highly recommend ordering from this company. I was in deep search for a product that everybody else told me I wouldn't find until next year (e.g. 4 wheel parts). Autoplicity knew someone that had the product and made the transaction as seamless as possible. I know where to look for future orders. <br><br>One very happy customer!

Autoplicity has done everything right. no problems here. would buy from again.

Prices are very good. There was a slight issue with my order, but it was taken care of after being passed around to a few different departments when I called. Would order from them again.

This was my first time using Autoplicity.com. It was an easy site to navigate. They had everything I was looking for in one place. The prices were reasonable and in the ball park for what I was looking to spend. I received confirmation of my order immediately and an email when my items were shipped. I will definetly shop Autoplicity again.

The prices were affordable and of good quality,I will order from them Autoplicity again.
