Remflex 2006 Exhaust Gasket for Chevy V8 Engine (Set of 2)

Overview

The Remflex 2006 Exhaust Gasket is designed for Chevy V8 engines, offering a robust, reusable seal between header or manifold and the cylinder head. Built for small-block power, it accommodates a 1-3/8 inch by 1-1/2 inch square port and ships as a convenient set of two.

Key specifications

• 1-3/8 inch width x 1-1/2 inch width square port; matches the stock cast iron head port on Chevy V8s
• Port configuration comparable to Fel-Pro 1404
• Includes 2 gaskets per set
• 100% flexible graphite with no rubber binders or composite materials
• Designed to resist shrinking or hardening over time or with heat
• Tackles gaps caused by flange warp through thickness and compressibility

Why this gasket stands out

In typical exhaust setups, heat cycling can cause flanges to warp, creating elusive leaks. The Remflex gasket’s graphite formulation provides a consistent, compressible seal that adapts to those changes, helping maintain a steady exhaust seal across temperature swings. The absence of rubber binders or composites means the gasket is less prone to age-induced changes, so you don’t have to chase leaks with frequent retightening.

Real-world use cases

Classic car restorations, performance upgrades, or routine maintenance on Chevy V8 builds can benefit from a gasket that aligns with stock port geometry while offering long-term stability. Expect a more straightforward restoration or upgrade experience when sealing between head ports and exhaust components.

What you get and compatibility

• Two gaskets per set
• Compatibility with Chevy V8 small-block engines (SB 262, 265, 267, 283, 302, 305, 307, 327, 350, 400)
• Suits stock head ports, manifolds, or headers
• Port geometry matches the stock configuration, with performance-oriented similarity to Fel-Pro 1404

Notes on durability and maintenance

The graphite-based material provides a durable seal across heat cycles, reducing the need for frequent flange bolt retightening and resealing. While installation and torque practices vary by application, the gasket is designed to maintain a reliable seal in typical Chevy V8 exhaust setups.
