in the proces of trimming this manifold to suit 2" carbs, looking at the rather large vacuum holes in the top of the runner. is this standard? is there a reason for it to be so BIG? if not i was thinking about plug welding and drilling a much smaller (4mm) hole hoping to create a tad less turbulence..whadda we think? is there a saving there?
