What is plug gap for ACT Delco Rapidfire in 1985 Chevy Citation 2.5 Ltr

SOURCE: ac delco says .40 gap, champion says .60 gap why is that?

It doesn't matter what either one of them said. On my car it recommends a .45 gap, I run mine at .32 as it gets a better spark using less energy to jump the gap. On a self inductive ignition system, a good spark is very important. If this were my car, I would drop it down to .35 and the plugs will last longer, and have better performance. There is absolutely no reason you should EVER gap them at .60. This is a low RPM motor, so .40 would be ok, but I would personally put them at .35, and roll with it.
