Default Re: How do you port and polish

Been reading quite a bit. I have a very clear sense of what porting is. And how to do it. I'm just a little unclear on how much material to take off with regard to the piston sleeve. It seems to me that the ports in the sleeve are considerably smaller than the ones in the outside housing, so I'd probably want to open them up to match the outside.
But won't opening the ports in the sleeve alter the port timing?
So how much material do you take off of where?
