Look into some 64cc heads. Do you have a compression rule? 12.5:1 pistons?

Well if you go to a 383 of course you will have more power. You never mentioned a cam. For cam bigger isnt always better. You need a cam to match your track and your setup and rpm range. You want to be in the cams power band at all times other wise you arent gettin the most out of your motor. You could call Comp they are really good with cams. They can help you out.
