Boring the injector bung holes. I used normal water to lubricate the bit so there wasn't any oil to soak into the aluminum and contaminate the weld. I had to constantly spray water but it worked fine. I already spent a lot of time boiling this intake in Simple Green so I didn't want to ruin the clean surface.
