It is a lot more complicated then just a pinout pic. You are switching a OBD-1 to a OBD-1. It dosen't just deal with the head. You will need a distributor and manifold also. It is a hell of a lot eaiser to just leave it OBD-0 and get a MSD RPM activated switch. If you really wanna go through the hassle I can walk you through it But I am warning you...you need to understand wiring. If you want help PM me.
