Exhaust Header Gasket Set for 1963-1989 Big-Block Chevrolet Mark IV
Color:
Header gaskets take the worst of it: full exhaust temperature, constant cycling, and a flange that moves as it heats. At 0.0625 in. thick these give enough compliance to seal a header flange that is not perfectly flat, in a two-piece layout so each side installs on its own without wrestling one long gasket into place.
Edelbrock 7205 Header Gasket Set Specifications:
- Two piece exhaust gasket set, six bolt holes per side.
- 0.0625 in. thickness, black.
- Fits big-block Chevrolet Mark IV engines, covering 1963-1989 Chevrolet and GMC.
- Suits headers and cast exhaust manifolds.
- Retorque after the first heat cycle, since exhaust fasteners commonly relax.
Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.
Edelbrock Exhaust Manifold/Header Gaskets are constructed of htx-900. A high density non-asbestos fiber/metal core composite material consisting of two graphite coated, heat resistant fiber blended sheets that are chemically fused to an expanded steel core. The finished product provides high heat resistance, excellent lead retention and un-matched sealing performance on exhaust manifold and headers. A 50% recovery rate allows for gasket expansion in the event your header losses proper header bolt torque.
