i'm curious as to how i know i have a jdm sohc zc head such as is their the stamp on the head that tells me what engine it comes from???

 

bump not sure .. i have sohc zc and its just like a a6.. the cams is supposed to be slightly more aggressive although.. if your swapping a6 to zc don't do it unless theres something wrong w/ your a6 .. the gain is probably very minimal compared to the work involved .. and if your tlaking about the jdm sohc-vtec head.. i think the plugs wires are the opposite position front/back then the a6's, might also say vtec
correct me if i'm wrong :-)

 

i had one, and i'm pretty sure it was stamped something OTHER than PM6..... can't remember off hand what though, or maybe I'm just smoking rock....

 

i ask because i got a free "zc" head and actually its stamped PW3-Z so its definitely not a plain d16 head.
