I Know someone who is running a pair of #8007 390 cfm Holleys on his dual quad 428FE and loves them. Crisp throttle response, great acceleration, and better fuel economy than with a single 750 cfm carb. I'm not sure what jets are being run but his secondary springs are one step lighter than stock. The secondary carb linkage is adjusted 1/4" behind the primary. Of course, they look identical to the 600s externally. He takes his manifold vacuum source off one of the PCV tubes on the carb baseplate and everything seems to work great.
