Just got to be careful with the valves floating on your b16 head being that it stock. I dont see you haveing a problem but if you are going to start reving the motor that high you should think of a upgrade. Like retainers, dual valve springs cause I think the intake side of the b16 has dual valve springs and the exhaust doesn't there single. If you are thinking of putting you gsr cams there almost the same as the b16 if you want to upgrade why dont you go with itr or ctr cams.
