Its personal preference for a K swap or a H2B swap. Pricing will work out close to the same once all mods and bolt ons wanted are achieved. Pricing for a H2B wont be cheaper unless you are sourcing parts and are experienced at this. For the personal builder who has to pay to get through there build i believe you wont get much change going K or H2B. As for personal opinion im biased to K series as driving a K is like using Pentium 4 compared to driving a H is like using Pentium 1. Good luck with your choice making
