Andrews 54 is a nice cam for that setup... Check out GMRPerformance.com their dyno section should give you something to think about...
Woods TW-555 is another cam that will work good with your setup.
I am running 107" 10.5:1 with the Woods TW-408-44 and it rocks.

Heads and cams on your 103 would be a good choice. You know the exhaust will come into play. Depending on what you have now.

Those 254e cams are fairly short duration, you could put cams that have in the mid/upper 240's duration and maybe get a nice gain , keeping the lift reasonable(so you can leave valvetrain alone) and the ic early(44 or earlier) you might not lose too much low and gain a bunch of mid and it just might pull real good till the limiter. Just a thought.
