Is it worth getting a more aggressive cam if you don't port the heads or intake?? and if so what types of power gains would you expect?? ( that might be a stupid question)

VS cam without port. With port call comp cam and get a recommended grind based off mods. Roller rockers also kick *** .

I think alot of cams work better with stock heads Aggressive or not.

The gains to be found in ported heads dont come from porting and polishing, just larger valves [img]smile.gif[/img] If you want more performance from heads, throw some bigger valves in them [img]smile.gif[/img]

Thanks for the input.. Would I be able to purchase bigger valves at say like Advance or Autozone or do they have to be specialy ordered??

You know valves aren't exactly bolt-in, right? They're on the underside of the head, not like the rockers which are *cough* only underneath the valve covers. So to just do valves you'd be pulling the entire valvetrain to get to your heads, and you'd need a boatload of gaskets and bolts. Might as well shoot for doing more than valves while you're under there, since you have the expense of all the gaskets / prep / lube / bolts already , which may be more than the darn valves alone.
