The static compression ratio is not as important as the dynamic compression ratio. If the camshafts are changed and intake valve closing delayed the dynamic or effective compression ratio is reduced. If additional static compression is not added to offset the compression lost to a cam change the power will not be optimized. This subject is long overdue and yes "balance" is required.

I will slide back into my corner now as I expect this will be considered wrong by someone or another on this board.
