Hold on there killer!
Before you port anything, I would suggest a little basic understanding of what you are doing or you may end up with an expensive experiment....
You would be porting the cylinder, not the head (2 stroke).
Yes, you'll have to take the cylinder off and dremel all the way from the beginning to the end inside the cylinder (all the way through). Do you know how much or where to remove material?
I would suggest that you try matching the exhaust gasket and exhaust mounting flange to the exhaust port first. Once you do that, you will see an improvement and you don't have to remove the cylinder to do it.
Also, get some miles on the engine....like 2-300 before you worry about how fast it will or won't go.
