First Engine Build

It's getting closer to time for me to pick out a cam for my build. I have decided not to go with hydraulic rollers as I think that it would require to much modification of my original heads. I am going to go with a flat tappet hydraulic cam.
I know that the Comp 268 and Voodoo 268 have been suggested. I'm not looking for a choppy idle but would like to increase performance over the factory grind. Any other cam selcetions to think about?
