I went over my Friends house just now to shoot some pictures of his CAMS.
He has a 2007 GT and pulled the Cams at 30,000 miles, he replace the heads with Livernois Stage II and COMP Stage III (127600)He have Always Used Mobil 1 Oil and Filter and nothing else, changed Oil between 4K-5K miles. His Name is Marcspaz on the forums.
Would you be able to re-take the pics of your cams using the same level of light as you used on his? There is a lot more "flash" in the pics of his.
That being said, there are some pretty pronounced "tracks" on the back (or front)side of the lobes on his. Was he running 5w20 or 5w30? Were these the cams out of the "dealer replacement" engine that you posted the UOA for?
Mobil 1 5w20 No these cams were out of a factory Stock Engine. The UOA I posted was from a Friend (Adam) these are from Marc's Car another friend and Business Partner in FiveGuysRacing.com.
I will shoot some more Pictures without the backdrop maybe that will help.
Is it possible for you to borrow his stockers and take pictures of them next to yours?
