I was thinking more along the lines of filling in the area and blending rather than simply removing material around the shelf. That way it would have more of a uniform shape rather than the abrupt step that it has.

And that one genuinely is what I had thought. They built a mold to quickly and efficiently cast a head, not run like the wind.
What do you use to fill with?

I cut a head in half to get a better idea of the wall thicknesses and the amount of metal between the spring seat and the port ceiling.

I've got some disposable spares I can cut and take a look. Meant to do that before but just never got around to it.
Yep, there is not much metal to play with.

Thanks Armen , Seems nobody believed me how thin it is ! Used a different technique checking the thickness , a automatic center punch with the tip ground down to a ball with my finger on the other side , couldn't tell how thick it is but I could tell enough to know not to remove any material in that area just smooth it with some fine emery cloth !
