Frequently Asked Questions
Do I need to prep or clean the mounting surface before installing this?
Yes. Clean both the header flange and block surface with a wire brush or gasket scraper to remove any old gasket material or carbon buildup. A clean, flat surface helps the seal seat properly and prevents leaks.
What hardware do I need to bolt the header down?
This gasket comes alone — you'll need header bolts and washers. Refer to your K20 header manufacturer's spec sheet or service manual for the correct bolt size and torque sequence. Most K20 headers use M10 or M11 bolts.
Can I reuse this gasket if I pull the header off later?
No. Once a composite gasket is compressed and heated, it loses its seal integrity. Plan to replace it every time you remove the header. Reusing it risks exhaust leaks and oil seepage.
