Drivers manifold and a boxed frame

[bnokle]

I have the usual ls swapped lq4 into a 71" I boxed the frame so no drivers manifold with fit off the donor truck. Passenger side isn't a problem cause it has a turbo on it. I was going to weld on a v band and cut and grind off the flange. But after cutting off the outer part of the flange it hits no matter what. So mu question is what are guys using? I could use a trail blazer manifold that seems to go straight down or any shorty header. I'm looking for something that is known too work at least alitle better than the 02 manifold.
