Got a quick question. Just dropped in a 93 LS Motor in my 92 Civic EX 4 door, and my friend had a set of crower 404 cams in the motor. Is it safe to run those on a stock head, or shouyld I remove them and put the stock camshafts back in? Am I risking bending valves, or valve float or anything?

 

*UPDATE* car now starts and idles pretty good. Just need to adjust the timing, tighten up a few things, and double check all fluids and take her out for a little cruise. Throttle responce is a little on the slugish side though . . . . what could cause that?
