well if you decide to run all f23a1 there is a company bisimoto that will remake your cam to what you want, great quality. so then you can keep your stock low compression without having to screw with anything, and recoment garet turbo, i think i spelled it wrong, i know a lot of people runnging them in their hondas and they run amazing without problems with the turbos., and if you put the h series head on, why not the whole motor so you dont have to frankenstein it, i run a jdm h22a and i mean the thing is nice and solid
