Product Details

The Cometic C5215-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for GM small block V8 engines with Dart or Brodix aftermarket cylinder heads. This precision gasket features a 4.270-inch bore diameter and 4.500-inch bore spacing, making it ideal for performance and racing applications where reliable sealing under extreme conditions is critical.

Key Specifications:

  • Compressed thickness: .051 inches (51 thousandths)
  • Bore diameter: 4.270 inches
  • Bore center spacing: 4.500 inches
  • Multi-Layer Steel (MLS) construction for superior sealing
  • Designed specifically for Dart and Brodix small block Chevy heads
  • Compatible with high-compression and forced induction applications

Cometic's MLS gaskets feature multiple layers of stainless steel with embossed sealing beads that provide even clamping pressure across the entire sealing surface. The advanced material construction allows for thermal expansion and contraction while maintaining a positive seal, making these gaskets ideal for turbocharged, supercharged, and nitrous-equipped engines. The .051-inch thickness provides precise deck height control for optimal compression ratio tuning in performance engine builds.

didn't add shipping like other site did after saying free shipping

Great

Web site was confusing as to which part I needed but sales guy on phone got me hooked up with the correct part number so I could get the desired part. Order was shipped next day. Thank You.

There is a subcategory for the mazdaspeed model of the protege. Much less digging to find the right parts.
