Differrence is ZO6 valve springs???
Is there a difference in the valve springs (pressure rate, strength) used in the 2001 ZO6 compared to 2002 and newer??? They do have different part number...

Re: Differrence is ZO6 valve springs??? (SideStep)
I researched this when I bought my stock 2002 Z06 heads. The 2002 valve spirng is stronger than the 2001. The 2002 is about 295 lbs. compressed, the 2001 is about 265 lbs.
