Cams How do you choose one?

I don't know about that suggestion, they even say it needs headers...
Lift: .506 / .506, Duration @ .050: 220 / 220, Centerline: 104, Good low & mid-range horsepower, Needs 4-barrel & headers.

Typically you want a bit more exhaust duration, especially with manifolds...

I would do some research on how much the stock springs can take for lift, it's a good idea to buy the matching springs for the cam if you can.

You can find a cam that is bigger than the stocker that doesn't necessarily need headers. You will want a split duration with more for the exhaust side to make up for a little restriction.
