Great stuff Leon.
But I rather think with 500+ cubes that your 2nd gear will make a great 1st. Approx 80 mph @7000. Probably about what you'll want. That stump puller first will only be good for manoeuvering around in the pits!!
I think your maths are a bit out! If a 0.62 gear is 225 mph, then a 0.75 will be 186. For 205 you will want 0.67.
Edit: Actually Leon, now that I've had time to think about it, would not the easiest, cheapest, most effective way to achieve your goals, be to change your QC drop gears to give you your desired 205 mph? Doing that would then give you a 2nd gear of 77mph which would still be a pretty handy effective 1st. 3rd is not a bad filler at approx 135, and whammo, 205 in 4th! A racing, effectively dogleg first, three speed with those ratios would not be a bad thing, particularly if you're going to hook 565 cubes up to it!!!!
