I used the stock LA hose, but had to do some twisting and trimming to get it on there for the larger one. I just blocked the small one off because I'm not running a heater.
Are you talking about the outlets for the heater core or the bypass? I'm talking about the pre-bent hose that goes from the water pump to the intake manifold, I'm keeping the heater operational and both of those hoses seem to hook up fine.
I already tried messing around with an LA hose from O'Reilly and I wasn't comfortable with the way it fit; it 'went on' but was kinked and bent too much. I'll try one from NAPA they look a little different...
