The head on my parents EBII 4 litre appears to be warped. He has been told that machining will not be suitable so you either have to buy a reco head, or a brand new one from Ford. Is there anywhere that sells performance heads for the 6 at a reasonable price? If now what's the best option $470 for a reco one, or $710 for a brand new one from Ford?
