Now for the question if the housing has a small opening,

IT DOES, will it cause a cooling problem, seems to have for one. Not sure for anyone else

The narrow passage is only the feed ( back to the block ) lower passage on the passage side. All other passage look fine and closely match a factory housing.



Bashing aside... is there enough "meat" in the narrowed area to open it up to factory dimensions, with a die grinder and burr?
