Update:
I took it in this am, 1130 miles after the head replacements. The Service Manager documented that it used another � quart.
He shook his head and told me to come back in another 1,000 miles. I pointed-out that my 5 year In-Service date was coming up, but said they'd be sure to "take care of me."
They're fast running out of things to replace.
FWIW, the 1,130 miles weren't highway miles - not a whole lot of AFM kicking in.
