See the Difference: Accuracy You Can See
A warped head is the #1 cause of head gasket failure. Even a head that ‘looks’ clean can have microscopic high spots that prevent a proper seal. Our process removes just enough material to ensure a perfectly level surface, providing the ‘bite’ necessary for the head gasket to do its job for the next 100,000 miles.
