Depending on the methodology you test under, the numbers are very valid to monitor changes and tuning improvements. The pipes can definitely be a factor. The water pump is 6HP tops so drop that.
I proved by my own dyno testing for Lou's Stainless Specialty pipe development, that correctly designed pipes do not lose 100 HP. Lou's first pipe design was exactly 52 chassis HP less than his 2nd, enlarged and improved design. THAT design in turn was 5 HP less than open header collectors. The chassis number for open headers was exactly 15% less than the FWHP numbers the motor made with open headers so they correlated. Water pump included.

"That" being a shorter stroke, lower piston speed, lighter reciprocating mass, and aluminum accoutrements for a "faster revving" FE engine for the "harmonica effect" of buzzing fast up past six grand.

I'm advocating a long stroke combination because It's my understanding you prefer a high torque low revving combination. At 3.78, my stroke gave me just what I wanted-with a cam that worked up to 6800 and power on top.

Then DO IT! All can make you a 482 or 511 that's 630 / 650+. I just didn't know you want to use that kind of power - you never demonstrated that you used it in any way other than touring sedately.

I get encouraged then have to hang my head after you ask me something like this................ (sigh)
