double cut tapered carbide burrs would work a lot better.
your width should be about 1.045" all the way top to bottom to match the head opening, like you see there in the carbon/oil baked on deposits

whatever you do, don't undo the wing nut or the bolt! the engine will come apart the moment you try to start it!
First time? If so, I'd suggest doing the porting with small sanding drums instead of a carbide bit. The sanding drums can be had in different coarsenesses (and diameters) for rough cutting and smoothing. Sanding drums may take a little longer (not much really), but since you are working on plastic instead of metal this isn't a bad thing. With a carbide bit you can dig clean through the plastic a lot quicker than you think.
I ported my LS2 intake in 3-4 hours using sanding drums only and never made any gouge cuts I wanted to undo. You can see the results on my GTO website.
you do need to use light pressure and go slow with the carbide for a first timer. But once you get the hang of it goes very quickly. I do finish blending with a 80 grit sanding roll to make the corners nice and round and smooth it all up.
1/2" diameter carbide burrs are a good size. I port 3-4 intakes a week so time = money is why I use carbide to remove material quickly.
The same type of burrs in single cut style work well on the aluminum throttle bodies. Or a CNC machine if you have one of them in your garage LOL
Great advice guys! Going to be finishing it up today will update
Rinsed all the plastic crud out and set it in front of a fan for a couple hours
then installed it and went to get some gas
Seems to rev better but it is thirty degrees and i haven't driven the goat in forever
