Recommendations for waking up a 305?

[Moneypit]

I've got a 305 that I would like to get put a little more "pep" in. I already have a decent dual exhaust with headers and 2 1/4" pipe. I do not have the money to put aftermarket heads on(unless someone knows of some good ones for real cheap, lol). So I was wondering if someone could recommend an intake carb and cam setup that might wake up my engine a little. Im not looking for a hot rod out of THIS truck I just want to add a little fun. Thanks. -Moneypit
