Is This Legal Now???

Anyone seen the latest accepted SBC heads for S/S? I'm hearing they are bare aluminum castings that are not machined at all. Does that mean the runners and valves can be relocated? If this is true, how did those heads get accepted?

They are bare casting. In the cylinder head world this means no hardware. "Raw casting" is what you are talking about. They are done exactly like all other approved heads on the list. Just smaller ports.
