65-72 Chevrolet Big Block Exhaust Header Gasket
Seal your big block headers the right way with a purpose-built gasket engineered for 65-72 Chevrolet applications. Designed to handle heat cycling and prevent exhaust leaks at the manifold joint. Stops compression loss before it starts.
Do I need to prep or clean the mounting surfaces before installation?
Yes. Scrape the old gasket material and any carbon buildup from both the header flange and cylinder head. A clean, flat surface ensures a tight seal and prevents exhaust leaks.
What fasteners do I use to install this gasket?
This gasket does not include hardware. Use the original header mounting bolts that came with your headers. Refer to your vehicle's service manual for torque specs to avoid over-tightening.
Will this gasket work with aftermarket headers?
Check your header flange bolt pattern first. If it matches factory big block spacing, this gasket will seal. Verify port alignment before committing to installation.
