The porting is fairly easy to do too. When you look into the port, out to in direction, you should see a pretty clear shot into the cylinder. Just remove the material that interferes with the path. Pay close attention to the ledge just inside the port, if you put your finger in there you'll be able to feel a sharp-ish ledge, just file it off. The intake side you just want it to be rough anyway, usually the polish is for the exhaust side.
