GSC Power-Division billet 7009R1R is designed to rev between 3000-7500 RPMs for use with a 34-36mm Restrictor. The peak lift and aggressive profile design will require upgraded valve springs.
**If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case**
