I can do porting on most any cylinder long as I can get my tool in the ports.
What is it your needing out of the engine, not enough power or not enough rpms.
The 04 cylinders are nikisal plated bore & if any port changes are needed, the plating will need removing before the work & then re-plated after the port change. Cylinder bore re-plating prices start at 179.95.
If the cylinder has been used or damaged enough to have been sleeved with an iron sleeve, then porting changes can be done any time a bore job is needed.
My porting prices start at 250.00 & will be porting like a sponcered pro rider would need.
Thanks for asking,
Neil

its basically a matter of not enough power. i want to make sure im at no disadvantage from the 450's. I will think it over because i'm not sure if i want to spend the money to have the cylinder replated. The intake port on my bike is on the cases, not the cylinder, so will i still need to have the nikasil removed in order to port the exhaust port?

Even though it is a case reed engine, yes you will need to have it re-plated.
Any time you break the edge of the plating between the cylinder bore & a port opening the plating will soon start to flake off. Once it starts doing that, its not long before the cylinder & piston destory each other as well as the crank.
