The Exhaust Gasket for Pontiac V8 326-455 engines by REMFLEX is a critical sealing component engineered to prevent exhaust leaks at the header or manifold interface. Built for classic and muscle car enthusiasts restoring or maintaining original Pontiac V8 powerplants, this gasket pair ensures proper combustion gas containment and maintains exhaust system integrity. Whether you're rebuilding a vintage GTO, Firebird, or Bonneville, a quality exhaust gasket is non-negotiable for reliable performance and fuel economy.

REMFLEX exhaust gaskets use a proprietary graphite composite material that withstands extreme exhaust temperatures and thermal cycling without degradation or blowout. The Exhaust Gasket for Pontiac V8 326-455 features precision-molded port geometry with a 1.125 x 1.938 inch center port and 1.500 x 1.938 inch oval end ports, matching factory manifold flange specifications exactly. This dimensional accuracy ensures a perfect seat, eliminating the need for resurfacing and reducing installation time. The graphite construction also accommodates minor surface irregularities on aged cast manifolds, making it ideal for original or reproduction headers on mid-to-late-model Pontiac engines.

Mechanics and restoration shops prefer REMFLEX gaskets for their durability and repeatable results across high-mileage restorations. The pair supplied (REM12-004) covers both exhaust manifolds on inline or V-configuration engines, eliminating the need for multiple purchases.
