Did you notice any gains with the 084 carb?

I milled 25thou off the cylinder base, 80 thou [2mm] off the intake skirt, 4 deep finger ports alongside the transfers, gutted muffler, indexed spark plug.
The powerhead needed the 084 carb to feed it.
If I did it again I would install the adapter plate between the tank housing and carb. That way no one could see the mod thru the gap of the top covers. Countersunk cap bolts bolting the adapter to the tank housing with nuts on the cylinder side of the tank housing through the original stud holes. But maybe there was a reason I put the adapter plate on the cylinder side of the tank housing, maybe the larger hole in the housing took out those stud holes. Plus the hole in the plate would need a recession around its perimiter milled to accept the lip of the rubber intake manifold.
I'd have to take the carb off to see what I did.
Hours and hours of tinkering I did back then
