I have a set of 915 heads I just bought and are not going to work for my build. They are fresh from the machine shop and ready to bolt on. They have new guides, seats springs, seals and stainless valves. The bowls have been blended. They are 2.08 intake and 1.81 exh. they are 67 HP heads. they have had stainless exhaust studs epoxied in them. The valves have been unshrouded. The have single springs with a dampner that are good to .600 lift. if you have any questions let me know. Asking $800 plus shipping. There is more money in parts and machine work in them than what I'm asking for them. I can e-mail pics and will try to get them posted on here later tonight.
