I think that’s what Ron is getting to…. On the lower gear, the keyway engages the 4R notch, vs. the 0 notch, which is 2 notches to the left in your picture.
But you probably already saw that…. So I’ll let the experts take it from here…

It was not/is not uncommon to mess with that timing to dial in the nature of the engine. Most don't bother. With the power range expected of that cam, just go straight up. It may be advertised as a 290° cam but it is only 230° @ .050.

My experience in taking out some of the advance was a disappointment in the results. If it was a car with an automatic transmission that's a different story. It may pull "a little" harder "off of the line" but you will be looking for another top gear running flat out.

As made, it isn't even close to being radical. It's just going to sound like a spunky stock high performance engine at idle, which is what that profile is intended to do.
