I dont know if Id shorten it anymore, unless you need to set something up with a 7500-8200 rpm shift point.

We Shorten the runners on a LS1 intake during our intial testing. At first we we just blown away saw 20hp over the stock ls1 intake. But hang on. Then put the same intake on a performance engine and went down 19hp. The intake that made more hp would only do it on a BONE stock engine. ALl other testing shown the intake was crap even. We took and made pleniums smaller, larger, moved the inlet around, dropped the floor. If I remember correctly we cut up over 10 LS6 and LS1 intakes.
