Remflex Exhaust Gasket for Chevy V8 – Set of 2, 100% Flexible Graphite Seal for Stock-Port Heads

Remflex 2006 Exhaust Gasket set provides a durable, 100% flexible graphite seal for Chevy small and big block V8 stock-port heads and headers (set of 2).

If you need a dependable exhaust gasket that matches the stock cast-iron port shape on classic and modern Chevy V8 engines, the Remflex 2006 delivers. Built without rubber binders or composite fillers, these gaskets resist heat-related shrinking and hardening. They compress to fill gaps caused by flange warpage, helping preserve a tight seal between the head and manifold or header.

Will this gasket fit my Chevy V8 engine?

Yes — the Remflex 2006 is sized for square stock ports commonly found on Chevy small- and big-block V8s. It matches the stock cast-iron head port profile used across many Chevrolet engines, so it’s compatible with a range of models.

• Fits Chevy SB 262, 265, 267, 283, 302, 305, 307, 327, 350, 400 head ports
• Designed for stock port manifolds, cast-iron heads, or bolt-on headers
• Port dimensions roughly 1-3/8" x 1-1/2" square port profile
• Sold as a set of two gaskets for a single exhaust flange replacement

How does the Remflex material perform under heat and vibration?

Remflex gaskets are made from 100% flexible graphite, which maintains compressibility and does not contain rubber binders that can shrink or harden over time. The material adapts to thermal cycling and helps maintain a seal even when flanges distort from repeated heating and cooling.

• No rubber or composite fillers that degrade with heat
• Compressible graphite fills irregularities caused by flange warp
• Resists permanent hardening so flange bolts require less retightening

How does this compare to other popular gaskets?

The Remflex 2006 is configured to match port profiles comparable to well-known OE-replacement parts, offering similar fitment and sealing performance. Its all-graphite construction is a distinguishing factor versus multi-layer steel or binder-filled gaskets.

• Port configuration comparable to Fel-Pro 1404-style stock port gaskets
• All-graphite design vs. rubber-binder or MLS alternatives
• Engineered for classic Chevy cast-iron head ports and bolt-on headers

What should I expect during installation and service life?

Installation follows standard header or manifold gasket replacement procedures; ensure flange faces are clean and flat for best results. Because the graphite remains compressible and resists shrinkage, you should see fewer post-install retorques compared with binder-based gaskets.

• Clean mating surfaces before installation for reliable sealing
• Torque flange bolts to manufacturer specs; recheck once after heat cycles
• Long-term resistance to hardening means reduced maintenance visits

Who is this for: The Remflex 2006 Exhaust Gasket (set of 2) is ideal for DIY mechanics, restoration shops, and performance builders who need a reliable, stock-port replacement gasket for Chevrolet small- and big-block V8s. Choose it when you want a long-lasting graphite seal that conforms to warped flanges and matches common Chevrolet stock-port dimensions without the drawbacks of rubber-binder materials.
