That sounds like the best way to do it if you are going to do it.
I don't want to be a wet blanket, and my first post probably sounded that way.
If you want to use NOS, or make ANY kind of performance mod, just be aware that you MAY shorten your engines life....is that relavent? Maybe not.
I do remember finding out once, when building a "performance V-Twin" that there is a direct link between the lifespan of an engine and the amount of excitement it generates.
