The boos fitting goes in without clearancing. The clearancing is for the fitting that goes on the boss. I used a 1/4" air grinder with the conical grinding stone. I removed the plenum bolt close to where the fitting goes so I wouldn't accidently grind on it.

Don't think so. Nothing changed in mine except the DI regulated return install last summer. After the air got burped it became a lot quieter. This has a lot to do with fuel starvation of the #8 injector. Ford Band Aided it with the Long Lead injector. You have 7 AD injectors and 1 AE. In my case, because I have the RR, it didn't have that cackle when I installed the AC Stage II Injectors.

To elevate the need for grinding couldn't you use a 90* Elbow fitting?

The fitting that goes on the boss already has a 90° fitting. There just wasn't enough room to thread it on the boss.
