i found a thread on b cams but nothing really on d's i bought a z6 head and the mark i see on the cam is e431 cam looks different than stock cams ive seen on different SOHC cars in the past thanks for the help.
In the pics you cant see it very well but the marks are on the end where the distributor connects

 

anybody have some info on this

 

its a stock z6 cam, the reason it looks different is cause the lobes are pressed onto the core instead of the solid ground core your use to

 

thanks man now im just being lazy but what are the specs of the stock z6 cam
