Product Overview
A head-gasket leak, oil seepage, low compression, or a cylinder already opened for piston or valve work requires fresh seals—but new gaskets will not correct a warped head, cracked casting, loose studs, worn piston, or cooling-system fault.
This set reseals the upper engine joints included in the package. Compare the head, base, cover, tensioner, exhaust, and O-ring pieces shown with the service plan before disassembly.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Can this kit seal a warped cylinder head? A: Not reliably. Warped or damaged mating surfaces require machining or replacement.
Q: Does it include every seal in the engine? A: No. Verify the pictured contents against every seal needed for the specific top-end job.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
