MS260 Intake port shape

[Turner Saw]

I'm working on porting an MS260. Not being real familiar with this model I noticed the intake has a defined D shape to it. Those of you that have ported one of these before, do you stick with that shape or open it up more into a fully rounded shape. I have a nice used oem cylinder that I would like to do correctly. Thanks.

The boot has the D shape so I’d stick to matching that
