Read the plugs and piston wash, and make your own determination after that.
430's are stock and they are fat from the factory. I think 450 is gonna be too much. Personnaly I would start with the 430's. Again...the plugs/piston wash will tell you the story. Main jets are mainly for WOT. If your a little lean you won't burn down testing. Hold it wot for a couple hundred yards and check plugs. If too lean fatten them accordingly.
