All my comments are not criticism.
Is the exhaust opened up to the diameter of the exhaust gasket?
The exhaust could be polished shinier.
At the bottom of transfers I make that bump on divider a longer taper.
At the cylinder I make the taper smoother and a longer taper. Almost making a knife edge at bottom of steel liner.
The intake needs no work behind reeds.
The boost port I make a longer taper towards bottom. And a little more on sides. Make sure there are no boogers at port opening to cylinder.
