Check out Modern Performance. I have had good luck with them in the past, very good customer service, etc. They have top end and bottom end rebuild kits. And you can choose different parts depending on what you want - if you want upgraded cams, you can get them, if you want to stick with stock compression pistons since you don't want to turbo it, you can choose them too.
Check out the link here. Their top end kit is like 1300 and the bottom end is 1000.
