Stock 340 Manifolds or TTI Shorties?

Is this a statement of results, or opinion? I find it hard to believe no difference would be noticed on a stroker going from cast manifolds to headers. On the dyno my 408 made 25 more horsepower going from 1 5/8 headers to 1 3/4 headers. I'm pretty certain 25 hp can be noticed, manifolds to headers likely a bigger gain.

Manifolds on the track 9.1 in 1/8. Headers open 8.5 open, 8.7 closed. On the street those differences are basically nil, that is unless you plan on racing from every red light.
