Heads sold exchanged are guaranteed for ALL Cylinder Heads (not just new casting) for three years, Unlimited Mileage, as of Jan 2008, from the date of the sale. That is three years or true thirty-six months, from the day you received your head. The warranty is limited to the replacement of the head and all parts sent with the head except for the reasons below. We will pay a limited labor claim if the head has a problem that is determined by us to be our fault, in the first ninety days we will pay a goodwill labor, at a rate of $50.00 per hour up to but not above, $150.00 labor, and we will furnish or pay up to $100.00 for gaskets. This is goodwill and is only to make up some of the cost of removing a defective head. This is not meant to cover the entire cost of labor and gaskets only to refrain some of the cost. We sell a quality product and although mistakes happen they are very very rare. Please read the Must Read page of this web.
No warranty on any damages to the engine or driver (including passengers). No towing or rental car charges, hotel bill, or lost time will be paid. Labor is only paid if approval is given before the head is removed and only after being tested by us and found to be defective. Warped heads are never the fault of the head.
Loss of oil: Head run without or lacking oil or with dirt in the oil voids any warranty. The final say on whether or not the damage was due to lack of oil is us. Cam bearing failure is usually due to lack of oil.
