If you need it spelled out, have at it
https://www.holley.com/products/exha.../70301304-RHKR
"Max dyno gains of +8.59 HP & +7.3 LB.FT torque" for $700 + labor and small parts
That's max gains, not average, not mean, but max
Scroll through the pics of this link and compare the factory manifolds to the Holley.

For the gains Vs money, long tubes or don't bother.
