doug thorley headers

Just doing a little bit of research on this, in the Doug's Headers, they list D4477-B, that shows the later 5.7 header gaskets with EGR provision, presumably these also fit the 6.1 heads:

Every other listing I can find for Doug's D4477 shows the earlier 5.7 port layout, so maybe two versions available.

Sixpakchalle, is there any chance to get some measurements of these headers installed on the engine, most interested in the overall width and how low they hang?
