Yes....I was going to guess they flowed in the 320's.....not real bad...definitely room for improvement but you need to determine if it is worth the cost or if you want to attempt it yourself. I would still guess they are fairly turbulent form around .550" on up as the high speed air separates as it tries to navigate the short turn and then the radius of the smaller throat diameter...which coincidentally is probably helping your lower lift numbers a bit....work in different areas of the port will give different results at different lifts so you need to be diligent about how much you do and where
