I would avoid XE or voodoo cams. Very aggressive lobes that have a much higher rate of going flat.
vortecs have poor flowing exhaust ports so they do better with dual pattern cams. However, if you are using full length headers and free flowing exhaust the gains will be minimal.
Consider the old school 280H compcam (230/230). It will make a little less hp but will tend to live longer.
I would use a regular RPM intake (not air gap) with square flange and get a 750 holley 3310.
