I believe these heads came off a 90' 300zx motor (I bought them from a junk yard a while ago). These are extra heads that I have had in my garage with the intent to eventually build them and swap them with my own heads. I have since sold my car and no longer have use for them. They look to be in good condition, but I would still recommend having them decked just to make sure they are perfectly flat when you put them on your car. I am asking $150 + shipping ($30-50 depends on where you live). If you want pics just let me know and I will be happy sending you some.
