You need to look at what you want for end Hp/Tq, top end rpm s or more low mid range power and then make a decision on a cam choice. Cams are greatly effected by compression ratio. In general a low to mid range rpm cam will work well with the lower compression and a mid to top end range cam needs more compression.
For reliability I would stay around 9.5.1 and do a bolt in cam. You can go a little more agressive with both and be reliable. A good set of heads will make a good bit of difference.
