i just picked up my b16 head from a shop and i just want to make sure this is a legitimate head. it's supposed to be the CTR head for my LS/VTEC conversion. i know there's a code on the intake manifold that'd tell you whether or not this is a JDM head, but i don't know which code goes with which head. if there's another way, please say so. thanks!

 

Make sure the head says pr3-1,2,3 or 4. Look on the exhaust side of the head, above the header. The pr3 (b16) or p73 (itr) intake manifold will fit that head.
