Frequently Asked Questions
Will this gasket work with an aftermarket header?
This gasket is cut for OEM header dimensions. If you're running an aftermarket header with different flange thickness or bore spacing, test-fit before installation—you may need to source a matched gasket for that specific manifold.
Do I need new hardware to install this?
The gasket itself is the seal—you'll reuse your factory header bolts and studs. Check condition of those fasteners before assembly; if they're stripped or corroded, new bolts are worth the small cost to ensure a tight clamp load.
What prep is needed before I install?
Clean both the header flange and cylinder head mating surface with a wire brush to remove old gasket material and carbon buildup. A clean, flat surface is critical for proper sealing—take time here and you won't fight leaks later.
