383 problems

Hello, I'm having some serious issues getting my buildup to run right. I have a 383 4 bolt .040 over with flat tops. Sportsman 2s with 64 cc chambers, strip dominator(also have a air gap on the shelf) . I'm in high altitude so I'm running a avs thunder 650cfm. Lunati voodoo hyd flat tappet 268in/276ex 110lsa. Scorpion 1.5 in/1.6ex rollers. 1 7/8" sidemount headers with 4" pipes. Hei dist with a 7 amp module. 11mm livewires. Bm holeshot 2400 stall converter. Built th350 with shift kit. Independent 3 series Posi with 3.55 gears. I put in premium unleaded but I can't get it to run right. It ran strong with the 69cc chamber Sr torkers, decided to move up to 200cc intake runners. I'm running 36 deg total timing. What am I doing wrong?
Thanks
Dave
