I'm leaning towards the Ross units for a 59AB based 276 project. How does their dome shape compare to the chamber shape of the Ford 81A heads and the new Edelbrocks? I'd rather run iron but if the chamber shape is a gross mismatch and I'm going to have some time spent re-shaping I'd rather reshape aluminum. Also like John Lawson's thoughts on angle milling the heads to set clearances and keep area over the valves. This might be easier using AL than FE...Any thoughts? Never seen this group fail to have an opinion!!!
