340 T/A (U code) head value? (Pics)

I guess it'a all a matter of what you're messin with. I don't mess with small block stuff, so it's not worth much "to me". Sure, they're worth more than 50 bucks, but look at um. Then after you get um cleaned up, you have to "hope" they aren't cracked. Then after you spend 600-700 on them for new guides, seats and valves, you have to hunt up expensive valve gear. Since you're waving their flag, you can go buy um.
