A good used 4.2L straight port cylinder head, looks like it's had a skim recently but might be best to have it done again, the water ways look good as you can see from the pictures.

It needs to go to a new home so any reasonable offer considered. I'd prefer collection from Hilton in Derbyshire but I will pack…
