Installing Piston On Your Own?

How hard is it to install a Wiseco Piston. I'm thinking about getting one for my 300ex. What size piston would you guys suggest? Thanks

if you are mechanicaly inclined it won't be hard to do make sure you get a manual read and understand what you are about to do.
As for size I have been selling quit a few of the .020 for the 300ex and some people look into the 330kit.

how much does it cost for the 330 kit? What does that include?
