B18Civic1999

I have a b18b1 motor form what year unknow 94-01 I think it's a 97, anyway I did a headgasket a while ago motor has at least 200 xxx on it and is burning quite a bit of oil, I'm going to do piston rings stock bore, and I want to build the head with crowder valves or skunk 2 , if I get stock spec valves do I need to cam the motor as well? I am a little newer to this so give me a break, thanks guys!
