hi, a few weeks ago i bought a b7 head, but i've been reading that if the code of the head marks pm9-2 91, it maybe is an a6 head, this is because i'm looking for an a6 cam, but i can save some cash if i already have it

well, i guess i'll buy the a6 cam, thank you

 

Why a a6 cam? It's no better than a d15, the zc is the motor with a slightly more aggressive cam

 

i've seen a couple of cam specifications, and the a6 an zc seem very similar, i'll buy what i find first

 

Depends on which D15 camshaft you are talking about. Measure one, you'll see.
