Looking at your posted numbers and what is the most important in regards to over all performance is the average hp and Tq numbers .
The choice for me would be clear.
Let’s look at just the rear wheel torque difference of let’s say a 3.00 ratio with no first gear factored in or torque converter multiplication.
The header set up nets you 1368 ft lbs, and the manifolds net you 1317.
50 ft lbs is a big plus I would want at my right foots command !
Another way to look at it is that a extra 50 ft lbs makes up for your power losses of driving your water pump, Alt and power steering.
