headers or manifold for my new 350?

[guyryan100]

I'm putting in a new 350 and am wondering if I should go ahead and put headers on since I'd have to buy the exaust manifold any way. The engine I bought is relatively lazy - it is rated at 260hp from the manufacturer. Would headers make a positive impact on this engine? I don't want to waste the money - can I get a bit more power/economy out of headers or should I keep it simple? Oh, the truck will be a daily driver.

Any other exaust recommendations?
