gt-40 heads but i know nothing about them other than this they are brand new castings the box says "World" "FMS" and "SVO" the number on the box is "MS-1021" and on the head there is 3bars. and these numbers FIZE then right under it has AA and then down the head it has 22 and then under that GT

are they cast iron heads??? where did you get them?? sounds like regular gt-40 heads with 1.84/1.54 valves.. but without a pic I could be wrong??

yes they are cast my uncle has them and im about to purchase them he said he thought the valves where 185 so your numbers sound right there bare and new so what would be a good price on them?

without valves???? hmmmmm that alone will set you back a few hundred more for valves, springs, locks and retainers so for bare castings 150 to 200 max....IMO if you put over 500 in those heads I'd spend a little extra for aluminum at that point
