I had to order in a longer, slightly more expensive burr, to achieve what I wanted on the intake side. Not too terribly expensive.

It allowed me to finally get rid of the more pronounced ridge around the sides of the valve guide and blend it into the bowl more smoothly as well as open up the airflow around that pinch point.
Admittedly, there is more that could be done if you wanted to go over the top. Cutting back the valve guide would give you much better access to cut around the guide deeper and smooth and tail out the area just past the guide at the bowl to blend it in better.
This is the intake side now completed. All I need to do now is get this head milled and painted black.
