Whats a set these heads worth? I got a pair sitting in closet with a dual plane cshelby intake that came off a 69mach1. just curious

 

2 dollars, and i'll buy em right now

 

Huh? A 69 Mustang or Shelby would have a 351W, not a Cleveland. If so, it would not work with the 351C 4V heads.

 

if these are cleveland 4v heads, they will have a 4 in the upper left corner of each head, then they would be worth bucks, if there closed chamber heads a lot more, at least $600.00 for the pair.

 

Closed quench chamber 4V are more desirable than open chamber 4V heads, but both have port runners that are so big that they kill air velocity. Cleveland 2V heads are often the more desirable or the stock Cleveland stuff. With new aftermarket aluminum heads for the Cleveland, non of them sell for much. The right person might pay a few hundred for them.
