By the power of truth, I, while living, have conquered the universe.

I don't know. Daleks are capable fighters, but we forget a few things about the Flood.
1. The numbers. It doesn't matter how capable of a fighter someone is, when the Flood have numbers, it doesn't matter.
A single Dalek could destroy the entire race of Cybermen, a single Dalek killed hundreds of heavily armed men in Van Statten's complex, a single Dalek managed to break through the Time Lock and avert the death of Davros leading to the entire race of pure Daleks being created.
Numbers mean nothing against the Daleks.
2. If given the chance, I'm sure the flood would jump at the opportunity to infect other races, gaining access to ships and weapons.
The weapons in the Halo universe wouldn't do much against a Dalek. Technology in Halo is vastly inferior to technology in Doctor Who, especially the technology at the diposal of the Daleks.
3. Gravemind(s) are master manipulators, and can interface with technology. Who's to say they couldn't manipulate a Dalek or Davros himself?
Depends really, as I said before Dalek technology is well beyond that of Halo's. The Flood would have to act VERY quickly to get themselves a Gravemind as the Daleks can wipe out entire worlds very quickly.
All in all I think it would come down to if the Dalek's let the flood get into their later stages. When they get into their later stages, things become serious. For an example of this, it's pretty easy to say the Forrunners have equal to or more power then Daleks, and look how that worked out.
The technological level of the Forerunners compared to the Daleks is nowhere near equal, the Daleks had a bomb that would wipe out everything in the entire universe, the Forerunners had Rings that killed life in the galaxy. The Daleks could travel between dimensions, between galaxies, through time, can regenerate themselves when they're touched etc etc. They're completely unmatched, the entire universe almost lost to the Daleks before the Doctor used the Moment to seal off the Time War.
