Frequently Asked Questions

Q: Do I absolutely need to replace the head bolts when installing this gasket set? A: Yes, the original head bolts are torque-to-yield and intended for one-time use. Reusing them can lead to improper clamping force and gasket failure; this set includes the new bolts you need.

Q: Will this head gasket set fit the supercharged 3.8L L67 engine? A: This set is designed for the naturally aspirated 3.8L V6. For supercharged L67 engines, verify the gasket thickness and bolt specifications, as some applications may require specific variants.
