I would suggest not tapering all the exit holes,did this,ended up having to advance timing 3 degrees. A straight hole has a faster flow rate
than a outside taper. The flame front will take longer to transverse the cylinder. Advancing the timing will be needed.
Now a small taper on the bottom and rear exit holes will call for no advance,plus the engine feels more balanced,smoother,quicker rpm.
