Well...I just looked for these heads new...Best price I found was 300.00 a head just for the bare castings...Thats no valves, springs, retainers, locks...also mine has 7/16 screw in studs and guide plates. You dont get that with bare castings. Fully assembled you would have over 850.00 to 900.00 in these heads. Just so everyone knows what I am offering. I don't think the price is bad.
