The Hulk will fold Black Bolt. The only way that this would be close is if the Hulk allowed BB to range him to death. The current Hulk is leaps and bounds more powerful than the Hulk that BB defeated in the past. There are many indicators that support this argument, such as how easily the current Hulk dispatches characters that flat out gave Savage Hulk fits in the past. The Hulk is fast at close range in terms of how quickly he can reach his target, BB won't be dodging, nor will he be able to weather an onslaught of hits that the Hulk would rain down upon him. BB is powerful but up close, this would be the Hulk's fight to lose.
Can the Hulk tank a shout from BB? I would say that he could, and easily at that. Anyone capable of not only surviving forces capable of liquefying prime adamantium without being torn apart should be able to tank several seconds of BB's voice. How long would it take for the Hulk to get his hands on BB? Not long imo. How much force can the hulk generate from his own long range thunder clap assaults? Look at his feats. BB can give better than he can take, and this would be how he would lose this battle. The Hulk would continue to improve, while BB would continue to lose stamina.
Hulk 7-8/10
