I decided that im going to pick these cams up today , because i found them for a good price, but i wasent sure if i had to get valve springs and retainers for these cams. Im Not going to be reving over 8K, So do you think i need any upgrade in valvetrain? hopefully not. please help

Arent their Pro series, comparable to their stg 2 cams from old?

If so, I think they recommend to upgrade the valvetrain.

 

if u are not going to rev over 8000 rpm. stock valve springs and retainers are fine. i am running oem ctr cams with stock b16a valve sprints and retainers. and i never rev over 8000 rpm

 

Pro 1s need valvetrain. CTR cams do not even come close to the lift of Pro 1s.
