I wouldnt think theres a difference between the carbon in a fuel injected engine vs carbon in a carbed engine. Only issue i could see would be ruining sensors thats why I said take the MAF out and it happens to make a nice little pour hole too. But I definitely agree with you that he should probably start out with trying seafoam.
why not just use some of my 50/50 meth that I have gallons of sitting around? and seafoam that goes in to the brake booster line, right? Its been a while since I have used that stuff.

Yep, from what I've read
"The best place to use it on the 3800 is the brake booster line, which is connected near the fire wall with a yellow tip. That is the only spot it can clean all the heads from"- courtesy of Hippo.
