What cam should I use on 318?

I am restoring a 1968 Cuda. I have a 318. Originally 2 bbl but I am putting 4 bbl on it and headers. Replacing rockers, rods and lifters. Pulled it apart yesterday and decided to put a new cam in it as well. I've read some posts that are way above my knowledge level. I don't want to get into the tech details, I'm just looking for some suggestions on what cam I should use. Any ideas?
