it really comes down to who is going to port the heads. one option not mentioned is to get your heads ported by Chris Hinson and to then run a cam specced by him. IMO that would be the best way to do it. I am running an XP cam with a set of heads he ported before he was very well known in the 3800 community, and I went with that cam because that is what he recommended would work best with his heads.
edit for additional information: one other thing I forgot is the cam that Will from Overkill Motorsports specced, and he will gladly provide the details to get to get that cam built, he has 2 options, a small blower cam, and a big blower cam.
