I had the hot cam in the car, Im swapping it out for the cc306. Are the valve springs I have ok for that cam, or should I swith them. Only reason I just wouldnt do it is because i dont want to really take the heads off and im not fond of the idea of changing them while bolted down. Also I'm running 202 160 valves, I wonder if I'm gonna have any clearance issues?

thanks

lt4 springs wont work..dont even try. You can change springs easily without taking the heads off?

 

guess i gotta change em, which springs would u go with?? And what do u think about the valves?
