99-00 cylinder head...shipped 550.00 lower 48 Boxed ready to go.. bought for 95 NA conversion ...changed plan bought a 00 miata.

 

That's a pretty bad detailed description. Rebuilt(shop name), used, mileage, condition, pictures? You said ready to go so I'd assume it's rebuilt, valve job, shimmed, cams and decked. But I wouldn't assume for $550.

Just trying to help you out

 

I don't need your help to sell anything... if it doesn't interest you move on...dick.... its a used head off a miata...when you purchase it you can do all your assuming things you want to do with it. And if you've seen one used head then you have a good idea of what it looks like

 

I was about to ask for the details he mentioned aswell. You need a lot more info on here. a used head isint a used head, each one is different and may be good for one application but junk for another. Give us info and you will sell your head.
