Well Back sometime ago when The divider was Used They also did the whole Intake system as well. This pretty much is How The Lump port came about Becuase it worked much better.
I think the upper lump that you made,IF?? it only came to the front edge of the lower Lump this could maybe? be the way to go with the upper.
The reason I feel this way is That it could very well help redirect the air from Slamming into the back wall,As in simply redircting it in and around The back wall and the Valve. As it come down off the ceiling.With all the Heads I have here cut up.I'm going to cut another SO that i have a 100% of the Back wall leading down to the floor. Then I will rework what You have made, IF this is not a problem with you.?? To see what turns out to work the Best with the Lower one OR one on it's own.
God doesn't like ugly.
