You could always add just a little bit of plastic to the back edge of the front z to fill the gap between the upper frame rail and the firewall. It would take some of the visual gap away and make it look a tad better. Plus to after you get a set of headers in there depending on what you use, they may cover some of it as well. Other than what you're mentioning it looks danged good!!! Love the stance, looks better with the nose a touch lower.....
