Yes! I just heard back from Lunati this morning, and they recommended the following cam:

Part Number: 10120700
Previous Part Number: 60100
Advertised Duration (Int/Exh): 250/256
Duration @ .050 (Int/Exh): 207/213
Gross Valve Lift (Int/Exh): .437/.454
LSA/ICL: 112/108
Valve Lash (Int/Exh): Hyd/Hyd


Chalk it up to good marketing (TV shows, Internet, who knows where I picked it up), but I'm very inclined to select Lunati over Comp, Crane, or any others. No idea why, I just think better of them for some reason.
