Product Details

The Cometic C5321-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM SB2.2 Small Block V8 racing engines. This precision gasket features a 4.125-inch bore diameter and .030-inch compressed thickness, providing excellent sealing and durability under extreme racing conditions.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and heat resistance
  • 4.125-inch bore diameter optimized for GM SB2.2 engines
  • .030-inch compressed thickness allows for precise compression ratio tuning
  • Includes steam holes for proper coolant circulation
  • Embossed stainless steel layers with Viton rubber coating for maximum sealing
  • Designed to withstand extreme cylinder pressures in racing applications

Cometic MLS gaskets utilize multiple layers of stainless steel with advanced coating technology to create a gasket that rebounds and seals better than traditional composite gaskets. The MLS design accommodates engine movement and maintains a consistent seal even under severe boost, nitrous, or high-compression racing conditions. This gasket is ideal for SB2.2 engine builds requiring precise deck clearance and reliable performance.

good for hard to find parts

Very competitive prices and fast FREE shipping! Will do business with Autoplicity again!

Prices were very fair, had to check back a few times to the listing to determine if item was sold in pairs and/or individually. Overall however the product looks good.

I bought gauges from here and it was the best price around. They shipped it quickly and it should be here soon. Ill buy from here again.

BEST PRICE AROUND, HANDS DOWN. Shipping was fast and communication was impeccable. THANKS FOR THE PROFESSIONALISM.

Very good website. Easy to use. found the parts i needed and the order process was very easy since i could just login using my amazon account. Very convenient. Received my parts in a week.

I ordered this product and Wednesday in the morning and it was on my door step Thursday morning with regular shipping. The ordering process was super easy and the price was $35 cheaper than any other online retailer. The Rack is awesome, easy to assemble took me about 20 minutes by myself, put on my jeep hooked up the bikes and off I went, fantastic design, I highly recommend the Rola NV2 bike rack and highly recommend Autoplicity
