340 race engine $3200

Going tonight to look. Should have something wrote down tonight around 8. As of yet i'm going to agree that they are not x heads. But i can't say for 100%

if i get the numbers and find that they for sure are not Xs however I don't think it should kill the value that much. They are 2.02 stainless valve heads and they are good enough to get this thing in low 12s
