I ran 4 different shorty headers with full 2.5" exhaust on a J+P 306 with ported RPM heads and ported Victor Jr intake. Paul Silva always laughed and told me to put long tubes on. When I finally added 1-5/8" MACs, the powerband increased by 1000 rpm and the car was noticeably faster.

My car is not stock so not apples to apples...but I felt a noticeable difference in the seat of my pants with the long tubes vs shorties. Definitely makes more POWA!
