WANTED TO BUY: 1 GM 990 head. I have GM 990 heads on my Mark IV 454. I had the heads at the machine shop to have new seats installed. As soon as he started the very first exhaust valve it cut through to the water jacket. I am in need of either one 990 rebuildable casting, or a set of heads. I am really open to any options.
