Interesting. My tech said from 2010 part numbers changed. So I assumed cams changed too. I could be wrong hence why I started this thread. Thank you for the info though

I can't answer you question about cam specs but regarding part numbers, I often see them change while the actual component does not. At least the change is not percieved to our eyes.
Sometimes a PN change just means its coming from a different supplier.

I think only a couple top tuners can vary the cams.
Vtec can increase lift too. These don't, they can retard and advance each cam 20 degrees or so. Since its a dual cam head, the ECU can change the intake and exhaust relation as well.
I think the factory already has many many hours into the cams and has them running peak.
The cam variation is why the car idles perfectly but screams to redline with a nice broad torque curve.

Yes... I don't remember exactly, but didn't some years have a "softer" cam that would wear out and there was a new part that went in that was harder and lasted longer? The year might have been 2011 or 2012 where the part was updated. So 2008 and 2009 certainly suffered from this problem.
