so what i got is a d15b vtec-e and i want to swap an actuall vtec head on it, i was thinking a z6 head, what would my compression be and what would i all need to swap this head if even possible. i have been told the d15b vtec-e is the same as the d15z1 but i am unsure, oh and i am planning on boosting it, i got a p06 ecu converted to vtec and already chipped and socketed, and help would be great, thanks
