First engine build.

I have been looking at cams. Thinking the comp xe262 or xe268. Was leaning toward 268 but was thinking of pb and ac. Also wondering what springs for xe262 are needed. Would Rhoades lifters help much with these cams or would the benefits be seen with a bigger cam?

Also been wondering if 2.02 valves will gain me much for street use and these cams? Looking for more torque and not too high of rpm's.
