Welcome to the Family!
What type of input are you looking for?
I would suggest a new piston and a bigger cam. I don't like high compressin because of the requirement of race fuels.
what type of pistons are you thinking any links or sites you get them from
www.motosport.com has some complete engine kits at decent prices.
We also have a supporting vendor called www.kbmotorsportsonline.com

I would also go with a new exhaust set up, rejet the carb, and a good high flow air filter also. 69Quadracer has one nasty 450 and he would be the one with great advice on this.
Oh Yeah, welcome to the forums.
