Don't tap it in case you want to refit injection later on. best bet would be to machine up some plugs out of ally and use O-rings to seal them. I saw a set for sale on yahoo recently.

Hey guys
HelpIng a mate carb his small port 4age
We need to block the injector holes.
Best way to tap and screw in a plug?
What if I was to turn up some plugs that were interference fit. Freeze them then knock in, slightly longer then grind them down so inside of the port is nice and smooth?
