I also took some metal off of this area as you can see in the next 3.
If you compare this one to the stock one below you can see how I reshaped it to enlarge it a little.
The stock port.
If you look at the sides of the combustion chambers you can see where I unshrouded them a little.

Here you can see that I removed a little from the short side on the intake.

Here is where I smoothed the intake runner. I only went in about an inch and consentrated on the roof and walls.

You are doing some good here. It's just the ports are pretty good already. You might want to shorten the valve guide a little also, but not too much.
Just a little side note here; I (myself) like to have the runners/port on the intake about 1/16 to 1/32 larger than the port/runners on the intake. Right where the two come together. I really helps with back pulse.
We need to do the porting class soon.
