Mine had 4cc difference from one head to the other. I sent one head back and got lucky that It was closer to the one I kept. I ended up matching the combustion chamber volume and surfaced to my liking. The head I sent back had a low of 80.5cc. A set of victors I did also had some differences, just not as much.
