If it were I running down this rabbit hole, (LOL, and I kind of am....) I would look for a cam with the lift to near the heads limits, (flow of known) rising as quick a mild race grind on a 108 a line in the duration suitable for the job. The difference between the advertised duration and the duration @050 would be a good bit smaller than a “Comp Magnum” grind. I’d do this in a mechanical cam. Or a roller if it is a Magnum.
