Shorties might gain you some umph down low over the stock exhaust manifolds, but the long tubes will continue that trend throughout the power band over both.

I put those summit ceramic coated headers and a flowmaster american thunder 2.5in dual exhaust kit on my 355. It's does sound good but I can't speak to the longevity of the headers, only been 6 months.

Everything fit nice didn't have to fight with them. The header to head bolts just barley fit though, that's why you start all the bolts before tightening.
