This reminds of that old saying "When your only tool is a hammer...everything looks like a nail."

Here's a video of the conversion process done on a Bridgeport mill...still primitive but no fixturing involved. A horizontal boring mill or machining center can do it in a fraction of the time. Providing the video to a machine shop should be adequate to obtain a quote.

I personally know the Inliner who did the research and provided the block/cap for that now deleted Engine Builder magazine article nearly 2 decades ago. Anyone else who feels they invented something is mistaken.
