second off, i'm sure there are many good reasons why someone may have a perfectly good set of valves laying around... One for example would be the person decided to go with aluminum heads about 20 hrs after a rebuild, found a great deal on aluminum heads, and could not use his BRAND NEW iron head valves anymore.........
anyone have an idea of a fair price?
does anyone know what standard lenghts are, they came out of stock GM iron heads off a merc 500EFI
