First of all I will recomend to find out what is wrong with the ports on your engine and what you wanna do with it. Just to cut extra holes won't help you at all. You need to know what kind of modding are you about to attempt, what will be timing on induction , transfer and exhaust, how big you wanna ports to be, forms etc. After you make your plan what are you going to do, you will need protractor ( I guess it is right name for tool to messure degrees). You need to mesure your timings and make nessecary adjustment. I personaly don't like to use power tool for it, I preferd to use diamond needle files for ports on sleeve, on the cranck shaft there is no too much choices-dremel, with green color abrasive. To make adustment for ports on cranck case you need to use fine bores for dremel ( I use custom made out of dental rotory tool).
But again, before you decide to cut the corners you need to understand what are you going to improve. It is most important point in moding the engines.
