the flow characteristics of the y8 are where the difference lies. between that and the intae manifold design, the y8 is basically the type r of the sohc setups.

y8 head has gsr-like squared-off combustion chambers, thus offering a slight bump in compression. the intake manifold also flows better than the z6 equivilent.

its good for about 5 crank HP over a z6 head in an obd1 chassis.

i lookin to do a mini-me swap on my crx if you don't need either head how much are you willing to sell it for?

seems kinda silly to me that you swapped a y8 and a z6 and you don't know the difference....there is very little difference

why swap a OBDII head on OBDI? for like 5 more hp.. you should just rebuild the z6 and boost the shit out of it.

i recently did a mini me on my d15b7 with a z6 head.. im boosting it like no tomorrow and fuckin' gas prices have been going up ahhh
