Did you try hooking a timing light to each wire to verify spark on each cylinder coming from the coils at least? When I did the headers on my 2000 SS it started up and idled a little rough and smoothed out when I revved it. I put it in gear and it shook like crazy. I had forgotten to put the #8 plug wire on the plug! I remember waiting so it wouldn't get in the way of tightening the header bolts. But with the cam it probably makes it tougher to tell. If you pull the plugs you might find one that is covered in fuel.
