Why do you prefer the sealed power to the kb? I'm assuming the FHR are forged pistons? What would you run as far as a hydrualic roller ( not really wanting to go mechanical). I just dont want to go to small, but I don't want to go to big either. If I'm running 10.35 CR I should be able to run a pretty decent sized cam, right? What kinda Hydrualics you have lying around there?
