best headers??

I have a BB 4 speed a-body, I am reading the November 2008 issue of Mopar Muscle which has an article on Schumacher headers in a 67 Barracuda. It does not indicate if it is a manual or auto trans, but they rave about the fit and quality.
I called tti and they referred me to Schumacher.
I called Schumacher and the person I spoke to stated they have headers that will work with a manual trans BB, but said they are different from the auto headers.

Has anyone used the Schumacher headers with a BB manual trans?
