I say if the gap is larger than stock specs, get a higher output coil because widening the gap is going to increase the coil's dwell time (saturation,) which in turn will make it output at a higher voltage and possibly reducing it's life from operating at a slightly warmer temp.
Then again, having a coil with too high of an output will only eat up sparkplugs like PEZ under low compression ratios (8.8-9BAR)
Higher CR=higher voltage needed to overcome compression
Lower CR=lower voltage needed to overcome compression
