When you make so many changes, a tune is a MUST!!! You need the timing, fuel, everything adjusted/matched up to the NEW/DIFFERENT working PARTS.
Also these mods are for high rpm H.P. So that's another reason for gears.
Not only it takes you a long time to get to top/high H.P. but after every shift the rpm drops so much that again you are far from your high H.P. It's almost a miracle that you did this well.
Just get smaller/lighter wheels for the rear, plus a set of M/T or Nitto street/drag radials. You can drive with those to the track, then drive back home.

Umm I have cai, LTH, basically a straight pipe CBE and still running rich as when I was almost stock. There's no way he's running lean if I'm running rich. My motors well being is extremely safe at about 23-24 degrees of timing and 11.9-12.4 AFR. This was all logged and dyno'd.
I also don't 100% agree with lighter wheels/tires/flywheel/pullies etc on a drag car. When shifting the rpms will actually drop faster than if the car had heavier components that keep the inertia up and spinning. The OEM wheels are light enough.
