Sorry that I didn't word it right. So basically I need to make two custom intake manifold or one plenum going into both heads with the 4 runners on either side. Then I need to make seats for each injector at the base of each runner going into the heads...correct?

Then what about the fuel setup? With carb is there a fuel pump in the stock fuel cell like a fuel injected car has? Then i could use the same pump and fuel lines. I would just need a FPR and 2 fuel rails for each of the 4 injectors, correct?

After that I do the wiring harness from the ECU for everything including ignition and fuel injectors, correct?
