Manual adjusted valves are backed off to protect valves during shipping. No cam seals have been installed as one is included in most gasket sets. Limited Warranty Heads sold or exchanged are guaranteed for 90 days from the date of sale. The warranty is limited to replacement of the head only. Remanufacturer reserves the right of final say on whether or not the damage was done by lack of oil.
Cam failure is due to lack of oil.
Valves Manually adjusted valves must be set before startup and checked after 500 mile run-in. Valves bent due to shipping are not covered other than replacement of the valve before the head is installed. Defects Damaged parts or stripped bolts that are damaged will be replace if found before the head is installed. Damaged parts not found or damaged after installation are not covered. The loss of a heat tab or the melting out of its center will void the wattanty provided.
