ok i have a b16 and i was thinking of putting some skunk2 stg 2 or 3 cams. obviously giogn to upgrade the springs and retainers. do i have to replace the valves? also will the valves hit the pistons? or can i keep the stock pistons for now?

you can keep your pistons, but you will need to remove your head to replace the springs and retainers

 

anyone have any advice on a brand of cam that they preffer and y they preffer it?
