Hello Mate. I don't think there is an area on the front bulkhead that you need reinforce.
You will need to tread carefully when drilling large diameter holes for vent pipes, but that is to avoid the track rods (amongst other things) as they bounce around during normal driving usage.
Note that there is a
hidden pipe connecting the cockpit and the front/boot area, but it is blocked at each end - you will need to drill out the 'glass, I plan on using it for ventilation on my build.
