Eddy 75 CC heads or 80 CC 440 Source heads
The carb and exhaust are smaller than I would use for a drag only car but the parts you have aren't a really bad start, go for it
Make sure and degree that cam in so the intake lobe center is advanced at least 4 degrees up to 6 degrees advanced to help the bottom end with that converter
BTW, did that motor come out of a Chrysler or Imperial? Is it TNT motor? Did you measure how far down the pistons are from the block deck?
I've had several 1966 440 blocks that came out of Imperials and Chryslers, one of them was a August of 1966 casting date so it went into a 1967 car, not a 1966 production Mopar
