Used cylinder heads are evaluated on a "case by case" basis, in which they are subject to extra charges for labor/components required to present a turn key product.
Extra charges are added as a seperate bill after our assessment, and are made aware to the customer before any work is performed.
Performance Driven Design is not responsible for any shipping fees to return products if the customer does not want to proceed.
A $250 fee will be retained after inspection if the customer does not want to proceed with the porting services/services required to present a turn key product we can safely stand behind.
