For sure it needs lowering. Remember the other point I tried getting across. The common wall slants in, the roof slants down, and the floor slopes up. Each of those areas plus the pushrod side wall has to be worked.
That pushrod side is about as tricky as the short side. Too tight a radius and you've lost it.
As far as the roof goes, I've found the cyl center side needs to be lower and straighter than the common wall side. On the cyl center side the air wants to go right to bore center. On the common wall side it will follow the roof more.
