On my '01 Ram Off-Road package truck I wanted to move the power band up to work better with the 4.10 gears.When I pulled the intake to fix the plenum oil leak,I shortened the runners about an inch & radiused the port entrance.I also ground off the raised lip above each throttle bore and radiused that as well.This made it more responsive and it did work better,less downshifting in high gear/OD when towing. This site shows some Kegger intakemods and sellls parts as well:

On my 87 Dak , we tried a lot of different thing to get it work.....My Ex Hubby and my Uncle cut down runners and epoxied baffles... next step was buy an Airgap intake manifold......, this photo is not mine, but it's similar to the mods they did to my kegger
