Milling heads and flow #s

If you reduce chamber volume a lot, say 76cc to 63cc would that effect flow numbers? Just wondering if you remove to much material does it have any impact except for increasing compression ratio?

Thanks

You would definitely see a higher ratio. What is it right now?

If you're simply milling the head, typically, yes it will. As for how much of a difference, the shape/configuration of the chamber has a lot to do with it.

You will defentially loose some air flow, but the increase in compression can more then make up for it in HP.
Most heads dont loose a ton of flow but there is normally a loss.
