Probably. Those who have significant positive results have been beat up by the trolls and naysayers so that few people will share the progress.

I suspect the newest chamber tech and direct injection are making grooves minimal value.

Singh designed these for the ancient 2 and 4 stroke carburated engines in high BMEP conditions with junky gas. We still have junky gas... lol. I saw my first set of grooved heads in 1962.

Doing a set of full-up 289 heads now for a 5.0 f.i.
