There is a LOT more to porting cylinder heads than just getting a die grinder and removing material that YOU think will improve airflow!
The size and shape of the ports is very important and, the size especially, needs to match the displacement of the engine.
The guys that are really good at porting, usually have sectioned (cut into slices!) the cylinder heads that they port, so that they know where to remove material, and how much to remove, without hitting a water jacket, or an oil gallery, to achieve the ideal port for that particular head.
The only thing that the average person can really do, without any porting experience, is to "gasket match" the ports, and a general clean up of the casting.
If you are interested in learning how to port cylinder heads, there is a TON of information and videos on the internet. And, you can buy kits with everything that you need to get started.
But as Rap already mentioned, I'd practice on some old heads first, because it is likely that you will make a mistake or two.
