This is a tough battle. Gordon's weapons might not pull through to must Flood forms. The Crowbar could do well against infection forms, and POSSIBLY combat forms, as he can swing very hard to hopefully take it down. The Shotgun however, should most likely do very well against most Flood forms, as both barrels can be fired at the same time, doing more damage. The SMG's rounds can destory almost all of the Infection forms, and the Grenade can do massive damage to all forms. The Gravity gun, may be the weakest weapon in this scenario, as Gordon can only kill Infection forms with it, but he can fling obsticles in the direction of the Flood.

The Flood's forms, and their weapons will most likely succed in this battle. The Infection forms can latch on to freemens head, but not his body, as the suit can protect him. The Combat forms have overall, better weaponry than Freeman. Carrier forms may catch Freemen off gurard as he has not faced The Flood before, and does not know what to expect from the Carriers. The Tank, and Shooters can work together at the same time to take down Freeman.

Overall, I see the Flood winning this due to their weapons, and strength.
