Yep, the "smog" motor you refer to is the 32V '86 engine for Australia and Japan and a few other locations (Switzerland possibly?) - it is indeed lower compression than the US one.
Means that a hybrid S4 heads on RoW '86 5.0L block comes out with around 10.8:1 compression. One of the guys here in Australia has a track car with that setup.
I have one of the non-US 32V engines sitting in my garage in the corner - been meaning to dismantle it for a while now to get the cams modified for one of my S4's, and to measure wall thicknesses etc. on the block. I need motivation to do it tho', instead of the jobs on my cars that I've got on the list.
