What year, which D15/D16? For example, the D16a1, D16A6, and D16Y8 motors all have different heads.

The only other head that will fit on the 84-87 D15A3/EW motor is a DOHC D16A1 head which is called a Hydra swap. You will however have to construct your own bracket for the timing belt tensioner pulley. This swap is for people who are up to a challenge and don't want to bother swapping the whole D16A1 motor. NO OTHER D-SERIES HEAD WILL FIT ON THE 84-87 D15/EW MOTOR!
