so true but their very close. The Tomei's have a degree of 260 duartion on bother while the JWT have a 264 degree duation on both. and the lift on tomei is 11.2 on both, whil JWT lift is 11.43 on botherAt the prices I have found (about $375)...I'd almost be willing to guinea pig the Tomei RR cams. But the JWT S3R's have more duration and lift than the Tomei's.
Look through the 'notes' sections. JWT has some for the RR there called the S3 Roller grind. Also Tomei has some for the RR with 260duration and a 11.3lift i thinkSo which on those list are for a RR? The only ones I noticed were the piper cams, but I'm sure there are more out there.
