[DeTomaso] modified port plates for 180's

I am interested if comments regarding the use of port plates to modify the exhaust port so that it does not make a 90 degree turn  exiting the head perpendicular to the cylinder bore, but rather making a shallower turn which results in the port comming out the top of the head adjacent to the valve cover.  The head would be wider than stock but not as wide as when you add the width of the frist header bend. We try to make the intake as straight as possible but I haven't seen anything about making the exhaust as straight as possible.
 
Is there anything to be gained?  If so what and how much?
 
 This should work well with 180 degree headers.
