FAQ

Common Questions

Does this include head bolts?

No, head bolts are sold separately. Always replace head bolts during head gasket service - they are torque-to-yield and cannot be safely reused.

Will this fit both NT855 and NTC engines?

Yes, this gasket set fits both NT855 (naturally aspirated) and NTC (turbocharged Big Cam) variants. Same head gasket design for both.

Should I have the head resurfaced?

Yes, always inspect the cylinder head for warpage and have it resurfaced if needed. A warped head will cause the new gasket to fail quickly.

We offer free returns within 30 days if the part doesn't fit or you're not satisfied. Parts must be unused and in original packaging.
