I'm surprised somebody hasn't developed these for our (aircooled) engines; maybe they're used on the water cooled lumps, no idea.
It isn't obvious, but if you treat the holes like short "slots" you can get finer adjustment than just putting the pin in the hole and torquing it down. Getting the cams timed th same side to side is generally considered more important than their absolute value. I like to use 2 dial indicators, one on each bank. That way if I run out of adjustment in the sprocket "slot" on one side, I can adjust the other side "back" to make them even.
