What did the flow bench think of it? Looks pretty well blended.

Now polish the exhaust ports! I would take them to a machine shop now and have them tanked and milled.

It will showcase your porting.

A flow bench is the only way to tell. If the table vibrates, you are definetely turbulant :0)

It's going to stall around .450 and not gain much after that. I can tell from just looking at it that the FPS over the short side is going to be WAY too fast and separate once any lift is achieved. Looks pretty though.

and sometimes that won't even tell you. You can make changes that will gain 5cfm and lose 20hp.
