I think the cam is a little on the conservative side, like you said.
Honestly, if you like the Comp Cams, I would look at the 280* Magnum or their XE series like the 284XE. I have the 274XE in my engine and I think that's not enough for my setup. I should have have 284XE also or maybe the 294XE.
A tech guy from Comp Cams told me the 274XE cam is more aggressive than the 280 Magnum because it has more aggressive ramp rates than the 280. I was also told that Ford engines like duel pattern profiles that favor the exhaust side.
Since you're going to have adjustable valvetrain, why not consider a solid flat tappet cam? You'll make a little bit more power with properly matched solid cam than with hydraulic.
I made the mistake of porting and polishing my stock heads without spending the extra money on converting to adjustable rockers so that I could run solid cams. I guess if I did that though, I would be better off buying a set of aftermarket heads.......
