We worked with English Racing on this profile to offer the 2.2-2.4 lower reving engines with mivec control a profile that would allow for more air volume in the cylinder to help fill the larger displacement engines and make more midrange and top end power. The 6009R2 is a high lift very aggressive profile with a short overall duration to keep a lower usable rpm band. The 6009R2 is designed to rev between 4000-8500 rpms and should be used with a stroked engine or added displacement engine. The peak lift of 12.1mm intake and 11.9mm exhaust will require upgraded valve springs and a titanium retainer with special attention to seal to retainer clearance. With the lift of this profile it is suggested to only use the 5041/5040 Ti retainer and spring kits do to valve seal to retainer clearance. The 5041 can be used to 40+psi and the 5040 to 32psi on the R2 profile at 8500rpms without float or flutter issues. The profile will work fine on the OEM Rocker Arm and the Zero-tick lifter or with the OEM lifter. We have seen gains of 25-30whp over the S2 profile on the stroked applications with much more possible when used with a ported head and aftermarket intake manifold. .S2 Specs .

Unremarkable
Ring Size: 7
The photos were expertly taken for sure. The ring is nice, decent quality, 14k as advertised but the design and stones are less than exciting. It’s nice, that’s about the best I can give it.
