72 Olds Project

I have 2 cleaned up and surfaced Ga heads. I do have the valves/springs in a container, but the machine shop said some of them were needing replaced. Also I have a C head that was cleaned and I think surfaced as well. I will need to check it again when I get home. That one is also bare. All have been checked for cracks. I am looking to sell them and/or trade for some 455 exhaust manifolds. Just let me know if interested. I am in Clemmons, NC. Thanks
