Honestly save the money on the cams and run stock gsr. Put the money you were going to spend it elsewhere like on an LSD.

You may not want to worry about the vtec head right now and put that money into QUALITY turbo components so you won't be needing to swap parts out later for better pieces, get the better pieces to start off. A good running ls turbo can put down close to 260+whp if you set it up right and tune well. That is more than enough for low 12's in an hf crx.
