180 degree (crossover) headers in full bodied Dart?

Does anyone here know of anyone running 180º headers in a full bodied A-body car? Is it possible? If so, how about on the street? I'm guessing no, but I think it would be really cool. I plan on going with Doug's D453 headers on the 360 in my '68 Dart, but if I thought there were some crossover headers that would possibly work, I would do those. Exhaust routing would likely be difficult, but it would sound so cool!

I'm talking about headers like these: http://www.schoenfeldheaders.com/mcrossover.htm

Here's an example on a Chevy: [ame="http://www.youtube.com/watch?v=r2pf1H926uI"]YouTube- Fire Am 180 degree headers[/ame]
