i admire your enthusiasm and can appreciate you wanting something that no one else has really done but seriously the theory and reality are about 10- 13 thousand dollars apart and if you dont believe me you have never really tried building a frankenstien motor of this proportion!

GA16DE head with all inlet manifolds.
no dizzy - you run coilpacks with a fuel AND ignition computer. use an electric oil pump. they're generally a priming pump and i will use them full time, but this will shorten their lifespan a bit. not really bothered as it's a thrash car. you need to get the crank pulley and cam pulleys as well to run the timing belt arrangement. that setup is a bit tricky - you need to use the stock pulsar belt somehow. the A block pushrod holes need welding and re-drilling on an angle to suit the oil drain holes in the GA16 head. also the GA16 head needs the same holes welded and drilled to match. the water galleries also need some work (mainly filling and reworking). all the head bolt holes line up (one you'll have to drill out an extra 1.5mm in

There was quite lengthy thread about this ages ago.
Did you say you had the valves opening and closing?
