I don’t think so. I think your current cam while mild for those cubes is better suited to 111 cubes.
Sometimes we get caught up in the advertised rpm range to the point we forget those descriptions are tempered by the size of the engine. Volume of air is required not only by power range goals but also by sheer size. 111 cubes needs more air than a w6 is designed to provide.
The difference in duration shown between the two does show power coming on lower in the rpm range with the w6.. but I’d assume even earlier it would be quiet a bit less power. You either hold the valves open longer (duration) or lift them higher. But you need a particular amount of air. The w6 on paper to me looks like a 9.5:1 to 10:1 cam for an 88” bike.

You might go back and read my reply to your thread on the same topic 2 years ago, I'd recommend you leave the cam alone. Mine was a disappointing turd with the super E that came on it, putting a super G on it made it come alive.
