Frequently Asked Questions
Do I need to clean the gasket sealing surfaces before installation?
Yes. Scrape off any old gasket material from both the cylinder head and exhaust manifold surfaces. A clean, dry surface ensures proper gasket compression and seal integrity.
What torque spec should I use when bolting the header back down?
Refer to your vehicle's service manual for the correct fastener torque sequence and specification. Uneven or over-tightening can warp the aluminum gasket.
Can I reuse the original header bolts, or do I need new ones?
Check your bolts for damage, corrosion, or stripped threads before reuse. If they're in good condition, they can be reused—just ensure they're clean and apply a light coat of anti-seize compound to prevent seizing on reinstall.
