X heads for sale

Ok I have decided to part with my 340 X heads. They are fully rebuilt with new valve seals, hardened seats, brand new Ferrea stainless steel (single groove) valves both intake and exhaust, and brand new valve springs designed for up to .600 lift and 120 lbs. They have no miles on them. These heads come with the stock shafts and stock rocker arms. Looking to get 850 plus shipping but I am flexible on price. They will be shipped in Edelbrock boxes. I will post up pictures when I get home. Questions about them pm me these heads are located in 98444. Oh yeah these springs were setup for a roller cam in my 340.
