I hate be a negative kill-joy but those numbers aren't so great. All your power is at the 4200 to 58OO rpm range way above your normal driving range. Also it will probably cost you more to drive than if you went with the vortecs and premium gas.
A GM vortec crate engine will beat those numbers by a long shot for just a little over $2000.
I hope you don't take this personally. I don't mean it as an insult to you in any way and I hope you get many years of good use out of your motor but I think your builder could have given you better advice.
