hi i was just woundering if you can run stock gsr valve springs with a stg 1 cam(like sk2,blox) if im only going to 8200rpm. I know you can with ctr cams and a stg one cams not that much bigger

 

google is your friend.
google the manufacture of the cam you are interested in running, and manufacturer website should provide information on what is recommended, and/or what is required

sk2:

Tuner Stage 1 Camshaft - B VTEC

Must use Skunk2 Racing Alpha Valve Spring and Retainer (P/N 344-05-1300) or Pro Series Valve Springs (P/N 311-05-5350) and Pro Series Retainers (P/N 308-05-0300).

blox:

Tuner Series Type-A Camshafts (B-series DOHC VTEC)

Upgraded valvetrain is not necessary, but is always recommended.

 

I would install dual valve springs on ANY camshaft upgrade in a "B" series engine.

 

You don't have to, but know the age of your valvetrain when decided.
