Just bought a head from a friend who got it from some 92-95 civic and says its a vtec head but hes not sure what one it is..the d15z1 or the d16z6. Is the anyway to tell?? with the valve cover off or something??

What ever it is I'm putting it on my d15b8 (cx model) block and need to know so I can match up the intake manifold, timing belt and spark plugs and wires. and what not

please help :) :)

thank you....
 
P08 would be the normal VTEC and I believe P07 is the VTEC-E/D15Z1 head.
 
Yes, and if you're popping the valve cover off to look at the followers- just count your followers and cam lobes. The Z1 has 16 lobes on the cam, the Z6 has 20.
