CYLINDER HEAD, REBUILT, FITS 1988-1994 XJ6. The price includes a $400 core charge that you get back when you send your old part to us. Comes complete with valves and cams, ready to bolt on. If your old cylinder head requires machining or welding there will be a deduction from the $400 core charge to cover the machine shop charge. There is no way to predict how much that will be in advance but it is important to know that you may not receive your full core charge back. We have no control over this. (JLM1705)
