Deliberate lean burn? I am just a fairing designer and am out of my element in trying to answer this question. Let me tell you a little story about the above mentioned streamliner in 1981. We did not know much about getting the best mileage so we ran it lean. Too lean. We burned a hole in its piston en route to the contest. Joe Minton was scheduled to drive that day. We pulled the head and my brother, Bruce suggested that we save the day by putting a countersunk screw into the hole and go back to stock jets. It worked. If you pulled the head today, the screw is still in the piston.
If you asking about changing the fuel-air ratios? Personally, I don't care. But in the unlikely chance that some DOT official comes sniffing around, it is your responsibility to be legal.
