not sure what you mean by that but what I was refering to is for example the boost port on engines (opersite the exhaust port) is meant to aim right at the spark plug. If its bored out the port will end up being opened later in the power stroke, so different port timing. Are we talking about the same thing?

Yup, same thing. Like for instance the exhaust port, starts in a particular shape (to get the port timing correct and prevent ring hang-ups etc) but as it approaches the exhaust header it becomes more circular. So, if you bore it you end up with a shape somewhere in between the two (probably narrower, higher and lower) and like you say, the timing is affected.
yeah thats a really good point, I didnt think of that
