Here is what I used with my 6.0 and Entropy.

Upper Gates 21439
Lower Gates 20687

Had to cut the lower, but they both fit great. You can look at my build thread to see them

Thanks so much....I ordered today. Another question-are you using the top port above the upper hose outlet for your steam vent?
