i have a 200 mile from new motor ( race port w 80 lbs minute worth of turbos and all the supporting systems) open and am wondering if it would be worthwhile to tighten up the sideseal/cornerseal gap from where it currently is at 3 thou.

if i tightened it to 1 thou would i see any measurable difference on a compression test... or inches of mercury at idle, or hp/torque.

if so, how much?
