I still have the article that Jeremy wrote about his 355 and he said he opted for the carbonfiber sports seats as you sit lower in them, thus allowing a small amount of extra headroom. of course, it isn't just about a person's total height, it depends how much of that height is due to long legs, and how much is due to a long body. If you have an exceptionally long body you might struggle to fit even if your overall height is less than that of someone who fits comfortably, as the distance from your seat to the top of your head dictates how much headroom you need.
6'7" and 220 here. The 360 is a nice fit. Havent tried on a 430 yet. Other than that, look to the front engined V12 GT cars for the best fit. If you have the means the 612 is a fine choice.
Steve AKA Solly is at least 6'5 250 # & he says the 246 Dino is a comfy fit for him I saw an NFL player that was also 6'5" + & he fit in a 550 but had to modify the seat
I think that you adjust to it. You become used to driving in a certain position and anything else feels uncomfortable, like sleeping in a new bed, but after a while you're fine. I am 6'2", 260 and I drive a really small car (Lotus Elise). When I first drove one, I weighed 290. I have since adapted and now other cars feel uncomfortable to me Maybe you need to take an extended drive.
