455 Heads
 

I have 3 set's. First set are 66's from 1971, Second set are 51's from 1975. The 51's have screw in stud's and guide plate's and the 66's are press in stud's and guide plate's. I also have a set of 4X but they are at the bottom of a pile so i don't have any more info on them yet. They are all good head's with no problem's. They will need valve job's done. $125 a set or $300 for all of them
