My theory is the cam oil journals weren't perfectly round or the tolerances were greater than stock.

The skunk2 manifold got released through a vendor on facebook yesterday. https://www.facebook.com/XPerformanceLLC/. They are in the process of a group buy right now for 750. Apparently they make almost 20whp so i was thinking about returning my cams and getting the manifold instead for more peace of mind.
My car is a 06 ap2, and it is not my daily but i do drive it often. I would like the car to go for 100k miles with the cams in it if it's possible.

Hopefully the skunk2 intake manifold does release soon...

I just upgraded my valve train to dual spring supertech setup(although not the extreme pressure just the first level) but ended up staying stock ap2 cams as the reviews are all over the place. Interested to see what people have made with the BC cams, I know in my old build k series, it had a fair amount of wear but I always blamed the aftermarket cams and the fact the cam journal bolts would stretch and the motor spun alot of rpms.

The BC cams make power. I had a 2.2 with a TP and berk header back exhaust. Tuned with Kpro they made 20hp on Church's dyno. That's a solid 13hp on normal reading dynos.
