Not intending to drill mine on a splash fed crank.
It is important that oil can flow through the bearing so check side clearance rod to crank
I would be looking for 012” - 015” clearance.
On pressure fed engines I believe you drill no 4 only to encourage flow through the crank.
It will be interesting to see other opinions
