Sparks plugs Gap?

[roadstar2]

Hi everybody,

Someone could tell me what Gap should I use with Motorsport plugs (one step cooler than the original one) on a 91 LX coupe 5.0L with 65mm throttle and 80mm mass air, 19lb injectors calibrated for the mass air. Fireball coil. ??? I've been told 0.54 but not shure???
Thank's

The emissions decal on my 88 says gap should be 0.52 - 0.56, which is why I always gapped mine at 0.54.

0.54 is wut I gap mine at
