I think your right wbute (PM sent) and thanks Greg. looking at my Torana's both cars cowls finish flush to the plenum. I was reasonably sure that the HQ-WB was different but since the last panel beater had buggered around with it and stuffed up the profile I started to second guess myself. Its been a long time since I have mucked around on the H series cars, and the memory defently isn't as good as it was in the seventies.
