Follow the directions of the ring manufacturer for gaps. As far as shortening runners, runner length and plenum size is dependent on the intended rpm band of the engine. A lot of math goes into runner length/size and plenum size determination.

7thou sounds like a fair old gap.
And as above, follow ring manufacturers instructions....and never too tight.
And by the time you fit a 2000hp IC on top of the intake and then the lid....how ******* huge is your hood that there is any change of anything fitting under it ? lol
