Your peak torque is right where my 512 runs best. Similar build but with a M1 intake and 4500.
To the original question if it was mine I'd run a 4500 carb. My set up really woke up after switching from the 950, 4150 Holley to a 4500. Also with the heads you have I'm confident that you will pull strong to at least 6300. I'm running basically stock Edelbrock Performer heads( way inferior to the TF) on my 512. I shift at 5500(most of my racing is 1/8th mile but in 1/4 I'm still pulling strong at 5900 when I cross the stripe).
But if you need to shift your rpm up some I have found the with max wedge ports you can move the power band up about 500 rpm.
In the extension i think i have to get my heads ported to Max wedge or bigger if it´s possible and if there is any gains in doing that. I already had the carb and my first plan was to get one more 950 and smack on my tunnelram, but it became a money issue so i just got the Trickflow intake. I do have a cheater nitrous plate under (150 shot), but that will on be a "if needed" option lol
