Help

I'm installing my v&h big radius and where the pipes meet the exhaust port, there is kind of a gap between the bracket and the head. Not sure if its supposed to be like that or not. I'm guessing it is because the flange nuts are fairly shallow and wouldn't be able to go all the way down the bolt. Anyone have the v&h pipes that can help me out? Here's the pic of what it looks like. Install is almost done....just don't want to go any farther if this isn't right.
