I don't recommend a PnP w/o at least a good set of cams or boost. Your engine simply isn't pulling in more air then your ports can handle.
However, I did manage to get a good decrease in spool time from the PnP that my machine shop did on my head.

I think they charged me 250 for the job. Good people. Just tell them Jeff w/ the Honda sent you.
