350 on any stock motor b, d, or h isn't safe. its been done, but its not safe...hell I'm gonna try to do it on my motor. in general though b series motors handle boost better than h series motors. you still need to tell us what the car is going to be used for...drag racing, autocross, road racing...daily driver? I have a lot of lag. if I would do it again I'd get a smaller turbo to eliminate some of that lag since I dont race that often.
