Is it possible to use a Z6 head with a Y5 dizzy? I'm buying a Z6 head soon and just needed to know that. Thanks.

nope, 92-95 sohc vtec-e and 92-95 sohc vtec engines are the only engines that use that bolt pattern. get a y8 head for your obd2 car, you'll thank me later when you see all the headaches that the obd2 guys with z6 heads.

or you can get the z6 head, use one of the z6 headbolts and 9 of the y5 headbolts. get a obd2a->obd1 conversion harness and run a p28. set your base timing at 16btdc with the z6 head and the p28 ecu. But then you'll run into an issue with the crank pulley because your obd2 d16 crank pulley has timing marks at 12 btdc instead of 16. so you'd have to get a timing gun with a dial and set it to 16 based off of the single TDC mark on the crank pulley. OH yeah, and don't forget to wire your obd1 z6/z1 dizzy to obd2

or you could just use a y8 head and swap the cam and the rockers with your y5 cam + rollerrockers. then swap ecus.

I think I'll take the easy way out and just get the Y8 head... But how would I wire the O2 sensor for the Y8? I know that the Y8 has only one 4-wire O2 sensor.
