Al,
There are ways to check all this but may seem complicated to those who are accustomed to a non- Ti-VCT engine. The cams would have to be checked with the cam phaser at the park position (no adv. or ret.) @.050.
Here is an independent evaluation of the stock Coyote cams.

The lobe lift they describe is exactly what is in the2012 Ford Manual DVD,
(.235in, .216ex) with a stock rocker ratio of 2:1. = .470 / .432 .
Where Ford- NHRA got a total valve lift for a Stock 2012 coyote of .519 intake and exhaust is beyond me, despite being over factored at 380 vs the Cobra jet 302 at 350....
Almost all the engine data and specs for the 2011- 2012 V6 and coyote are in this DVD... Borrow it from your local Ford Tech..Just set the date of your computer to the date of the dvd....
