GT40P Heads that were bought by a friend of mine on Corral. He hasnt run them, he decided to buy a built longblock I have and gave these to me plus cash. They are doing me no good right now so they are up for sale! They have 150k miles on them, alot of people have bought GT40P's from the guy he got these from and have been happy. They are off an Explorer, are unported and havent been used in a performance application yet. Thats all I know about them. $200 plus shipping! PM me with your zip code if you are interested! PayPal Verified & Confirmed! They look better in person than they do in pics, the flash made them look all dirty.
