Hi Charles,
I can understand your intent to 'do it once, do it right' so you don't have to take the blower off. Looking at the picture of your block, and my similar broken one - there is a slight register plus a land at 90 degrees above it. I'd ensure the register is flat all round and stick the cover on with no gasket only Loctite 515 or 518 including getting a seal on the top edge with the underside of the ports?
Another aspect of this is to minimise crankcase pressurisation with a good breather. I've heard big Yanky V8's sometimes use a vent into the exhaust to pull a negative crankcase that reduces windage losses. But it sounds a bit of a stretch for me and I suspect the 'spit and hope' lubrication may well spit the whole lot out down the exhaust very quickly!
