Yes, if I’m understanding what the question is correctly, I was talking with Doug a lot about camshafts before the forest fires took his place a few years ago. He didn’t find splitting the durations to be any more or less effective than the same duration on both intake exhaust. I ran about 1 million simulation runs on performance trends with various camshafts that he’s tried and I’ve got similar results to what he saw. If you’re looking for that 0.1s difference to win a drag race yeah maybe but if you’re just driving it for fun on the street. You’ll never see the difference .
