i was wondering if there was a way to tell what camshaft my engine has. i have two b16's, and i want to build a poormans type r. in one b16 the previous owner made claim (i dont believe him bc i havnt been shown any proof) that there were civic type r camshafts in place. i dont know if theres a difference in regular b16a and b16a ctr cams but if there is and if they reside in this head i would rather use that one for the pmtr. so if anybody can tell me where to look to get the identifying mark it would be greatly appreciated. thanks in advance.
