I would go with the second one assuming you can feed it well enough with the proper intake and heads. That looks more like a cam for a motor with 195cc heads and high flow intake like Super Ram or MiniRam.

I'd recommend cam # 1: Its more similar in profile to the LPE 219 cam that was designed for the superram. You would be quite torquey. I also highly suggest you spend some extra $ and convert over to a roller cam equivilant for added lift.
I'd try the 52mm and 24 lb injectors first, then step up to 58mm and 30 lb. only if the dyno shows you approaching 85% duty cycle at the top end.
