my next question is: do i pull the bolt in lumps to gain back some of the lost port volume?
The lumps are not hurting anything with your airflow,,,,,Hum,,
But on the other hand it is making your window port small.
Since you are not normally aspirated,intake port design is not as critical since you are forceing air into your intake port.
If it is not that much of a hassle,,,,,,try taking out the lumps & get back to us.
Best thing to do is widen & raise the roof of the intake ports.
The bolt to keeps your dividers lined up in the port, that goes into your intake manifold?
