so anyway thanks for the info, is there anyway to tell if the head has been milled in the past by eyeballing it? I heard once that there was a tab on the corner that is visible and it its looks like the number? is or something is not visible really good then it has been milled, also does anyone know where I can get a crankshaft advanceable gear, but just the crank part and not the cam part?

you can lead people to truth, but you can't make them see it!
