Thinking about doing cams want the gsc s2 cams and i know with this cam should do springs as well.
so what springs should i use and is valves needed with this install or stock valves ok ?

gsc s2 cams
springs
maybe valves
Anything else i should do while doing the cams ? I want least amount of down time possible would like to do this in one day if possible the car is my dd i do not have a nother car this is why down time is bad for me....

 

I would get the gsc beehives if I were upgrading the springs. I'd rather have a quality single than dual spring. And no valves don't need to be changed for cams or springs.

 

The cam will specify what is recommended. N I would just grab some BC springs.
