plan b

when all the parts i ordered for my zc show up, im going to throw it together. One problem. Not 100% sure if my d16a1 head is going to bolt up to my zc block. If it doesnt im going to try this out until i get a zc head. I have a friend with an si (88-91), a dx 1.5 motor (88-91 as well) and i was going to take my hf bottom end except pistons, and put in the dx pistons with some new rings, rod bearings and hone the cylinders. Take the si head and put it on the hf block. Take the si intake manifold and put in on so i have mpfi. And use the stock si header. But i was wondering if i would have any unwanted love between the pistons and the valves and what timing belt i would use.
