about 7-10 from both. from small engines like these honda, gains are small from bolt ons but the are nesscary if you plan in doing work in the engine.
To add to that:
If you're planning to more than just bolt-ons (all-motor build-up or forced induction) then you should plan out your list of mods very carefully from the start. IE: the mods you mentioned are a necessity if you're planning to put in more aggressive cams but if a turbo is in the near future then you've wasted $$$
