Safe to run ITR cams with stock valve springs ?
you should be ok - as long as you keep the stock redline - I myself would spend the $$$ and get new OEM ITR intake valvesprings (inner and outer) and switch your current GSR intakes to the exhaust side (because GSR intakes are the same as ITR exhaust springs) - BTW mike at IPS was selling new ITR intake springs for around 85.00 - that was a special tho - good luck
