Care to speculate my 340?

Focusing on the top end, What changes would you guys recommend to improve this build?
Maybe break it up like this:

Stage1 Bolt on:
* intake - which intake would you go with?
* exhaust - which header and exhaust would you choose?
* carb - which carb would you pick?

Stage2:
* heads - how would you modify the heads?
* stage1 - include stage one components with updates resulting from head mods.

This should be cool.

Thanks
