our 181/210 will do great combine that with a 62/14 or a 64/14 and you will have great bottom end. At that power level 60lb springs will be ok but I like ours much better. Use 24v lifters they are lighter than the CR lifters by far and will provide ample protection as well as handle aggressive ramp rates. I will be out of town for a few days but I will try to find an internet connection and check my pms. Also if you have any standard questions, feel free to call Ryan at 1-512-804-9015
