Keep in mind that the NHRA numbers are the minimum blueprint spec, not the as-cast numbers. I’m not sure about the 215 heads, but later iron Olds V8 heads tend to run 2-4 cc larger chambers than the NHRA blueprint numbers in the as-cast state. Obviously this also depends on how much the head has been surfaced, how much the valves have been cut, etc.
