When you go to full RPM on the starting line, the counterweights are going to close up some of the air gap which is why you need the gap in the first place. Also the reason why you need extra gap in the bellhousing for the throw out brg, otherwise the brg would start contacting the counterweight fingers at high RPM. Even with the line lock set, if the air gap is too tight, you can feel it tugging on the brakes, early disc failure at least. If you have the minimum reqd air gap, it's just a matter of RT from there. I always state my disclaimer: your results may vary...
