I did remove a lot of material around the valve guide and roof with the intake side, but not as aggressively as the exhaust. I focused a lot more on the shape of the port and blending areas together.

All of the transitions from the valve seat to the bowl and short radius were smoothed out or rounded.

The sides of the port walls were also worked to help promote velocity as well as free flow. You can note on the long side of the curve in the port (right side of port in 4th picture) was favored when removing material from the roof/guide area. This helped me shape it into a much cleaner and more direct line into the bowl and at the valve. The shorter/inside curve (left side of port in 4th picture) was reshaped more in favor of reducing the curve into the valve face and bowl, giving it a more gradual radius to help reduce turbulence.

I also opened up the bowl around the valve guide and blended it with the side channels created around the guide, but I feathered this out to the valve seat to help maintain more velocity.

The whole intake port now has a nice gradual arc straight into the valve and a nice gradual decreasing taper as it heads into the bowl area and valve seat.

A little more involved and aggressive than simply smoothing out the stock ports, but not so aggressive that my powerband shoul be shifted much. Only a dyno run will show if I achieved my goals for sure, but I am fairly confident I achieved what I was after.
