The 7008R3 is a high lift, aggressive profile for those wanting to push the 4G63 high into the RPM band. The 7008R3 is designed to rev between 6500-10500 RPMs and can be used with a larger displacement or stock displacement 2.0L engine. This profile is best suited for topend power for drag and standing mile style setups at 800+hp. The peak lift of 12.0mm intake and exhaust will require upgraded valve springs and a titanium retainer. It is suggested to run the GSC5078 or gsc5079 Ti retainer with conical spring kits depending on boost required.. 

The profile will work fine on the OEM rocker arm and the zero-tick lifter, or with the OEM lifter. 

**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**
