I have Jdm type s cams with, the type s valve springs and retainers. I use skunk 2 cam gears. and had them tuned for NA at +1.5/0. It should be safe to run NOS with these cams since they are JDM right? I know it would be safer if i put my USDM back on, but its a hassle. What should i do?

 

i know someone with a 150 shot wiht type S camshafts

 

Yeah it is safe.
