Frequently Asked Questions
Do I need to clean the header and block surfaces before installing the new gasket?
Yes. Remove old gasket material and carbon buildup from both the header flange and engine block mounting surface with a scraper or wire brush. A clean, flat surface gives you a proper seal and prevents exhaust leaks.
What bolts or studs do I need to secure this gasket?
The mounting hardware is not included with this gasket. Your 300ZX uses factory studs and nuts at the header flange — you'll use the OEM fasteners already in place. Have them ready and tighten in a star pattern to prevent warping.
Can I reuse the old gasket or does it have to be replaced?
Replace it. Exhaust gaskets compress and lose their seal over time, especially if you've had the header off before. A fresh gasket ensures no leaks and proper exhaust flow — it's cheap insurance against rough idle and emissions issues.
