You got a LOT of great opinions already. Tech is correct on many things and he is one I would listen to and trust and not have to think twice if he knows what he is talking about or not. The RHS heads he mentioned are supposed to be awesome heads for a street motor along with the Weiand Stealth intake manifold (I have one of these on a 351W and it's awesome)! As for the cam the roller cam is your best bet of course but some of us cannot afford a roller cam and can only opt for a flat tappet which is fine but like Tech said, you need to watch your spring choice and use the additives and just hope for the best after that because even with additives and a mild cam I have seen them go bad about 3 times in the past 2 years.

If this is going to be a daily driver truck, I would stick with a good highway gear (nothing above a 3.50). I know in my 66 F100 I have a 3.70 and it screams on the freeway so I have a 3.25 that should be much better for city and highway driving. Your gearing and transmission choice will play a HUGE role here. I would figure this out before choosing a cam and engine components. Stay away from those Thumper cams and high lift stuff and go with a nice low-mid torque street/towing cam. That will help with gas mileage, low end and economy, especially for a daily driver.
Do what is mentioned here followed up by nice flowing exhaust and a good set of tires and you will have a nice reliable daily driver that can still get up and go when you want. Later when you have the money you can build a motor, swap over the parts and heads after they are freshened up and keep going.
