gearing

my first passes down the 1/4 mile where good. but i am running out the 1/4 at about 5800 rpm. and my 60ft is down from my best. looked at all my time slips and i cut some 1.69 60 ft with 26" tire. now i have 28" with the 4.10s. i know i can pick my 60 ft back up with work on the car. and all this is on a 125 shot. my car runs best shifting at 5000-5500 rpms. and really dont want to turn it much more than that. my ? is when i start putting more mods on the car such as long tube headers, TB, and a bigger shot of nos i am going to run out of motor on top end. right? would going to a 3.90 gear be enough to make up for it? i fill like going with a taller tire than the 28" will slow me down.
