looking at your jets seem a little low to me.
in comparison my 440+0.055 with a M1 plus 1" open spacer and 825 mighty demon is jetted F78,R92 and when i run a Prosystems 1000HP Holley based carb is F84,R92
i do race with an air plate sealed to a six pack scoop
motor is 10.78:1,258/258 solid flat tappet
3/8 line for my motor was good with a holley black 150 pump to mid 11.3's then needed -8 lines
good luck
