1986.5 Nissan p/u not firing

Warped head on original engine (z24i) brother had an 86 with bad tranny so I pulled the engine from each and swapped them out, using the same intake and exaust that was on the truck. After completing the swap the truck will not fire, I was told the distributors were different, the 86 was carburated the orignial was tbi, so I swapped the timing chain cover and installed the original distributor and the same, no fire, I get a hot wire to the distributor and coils when the switch is turned on, but the plugs and the coils have no fire.
