They are all on the odd cylinders and the offset starts at 4000 rpm and goes up a tad as rpm increases on cylinder 1 but not on 3,5,7. The offset is gradually reduced as you move toward #7. I think your right about the angled entry which forces the high speed air right into cylinder #1 runner opening. Once I figure out how to post pics I can post a screen shot.
If this theory is correct someone could run into trouble if using this intake for boost on an engine without individual cyl fuel trims by running the odd bank a bit lean especially cyl 1 .
The 5.7 guys make nice gains when setting the SRV up to work. Here's a link to some before and after dyno runs with using it on a 5.7. Each graph has a handwritten note on what the graph represents
