all the D-series,SOHC heads are interchangable with each other....D15 or 16 doesnt matter...non-v-tec block+v-tec head equals higher compression better for n/a or N20

while a v-tec block with a non v-tec head lowers the compression makin it better for boost...

you can use any SOHC head gasket but the Z6(92-95ex/SI) head gasket is the better one to use...
