Any pics of the back of the head? Everyone always says that the distributer will hit the firewall, but I know that's just the internet regurgutation answer. If you use coilpacks, like in the pics, you don't have to run the top of the distributer (cap), making the assmebly a lot smaller. So, at worst (I think), you might have to clearance the firewall slightly.

I'd love to have one of these motors in a 510 or coupe. A little headwork, (do they make NEO cams?), and spin it to 9k, and you'd have yourself a nasty little NA car.
