Msd ignition plug gap ?????

I run a .050 gap with my eddy headed 410 sb.I run autolite race plugs,been this way for 3 yrs.I usually replace plugs at the start of the race season.

Complete MSD 7AL-2 step,Dizzy,wires,cap/rotor with SS Blaster coil.


I currently have my plugs gapped at .035 per the factory specs. i wonder if opening up the gap will effect my air fuel condition. just got timing all dialed in and its still running too rich. I am just trying to make sure all other variables are in check before i start tweaking on the carb.
