To go 1/10" smaller will not make any difference really.
And with going Intercooled, whether Full size or Short stack, you will have to tune for it to be beneficial ultimately.
Lastly, Full size's can be had for the cost of SSIC these days anyways, so if you do decide to do it, take that into consideration.
And one more though, with added power, you really have to consider what condition your tranny will be in. Most say that 300whp mark is the point where a completely stock tranny will begin to show its weak points.
