well hydrolocking in a flood this week blew the head on my car and I was wondering if all d series heads fit onto all d series engines. I have a jdm d15b so I am wondering if Ijust need a vtec head, will the 1.6 from an ex fit? thanks

 

yes the ex head will fit on there, they are the same head, but some people say that the d15b cam is a little more aggressive than the z6

 

they are the same head, the cam is the exact same also.
