I can't say for sure, but I was comparing them today (eyeballing) and it looks like it's only the top row of 4 studs for the D16Y8 that turns into a top row of 2 studs - as if they just put a single stud in between the two studs from the previous generation. I was pondering on the D17A2 swap for a 6G, and from what I can tell, the 6G Factory Exhaust Manifold has a bridge between the 2 swtuds of either side - allowing me to drill a provision for the single stud. Just look at the top row of a 6G manifold and you'll be able to tell. But the best way of knowing it to let him borrow your 7G manifold's gasket and just make a template or something to that extent for reference. Just some thoughts to help you on your way if no-one else does.
