906 Head shop

What kinds of numbers are any of you guys getting full porting a 906 head and still using the 2.08/1.74 valves?

I have a 906 that I have spent a lil time on 2 ports, I still need to do a valve job yet...but so far with brand new valve '2.08' im getting [email protected] lift

They peak just under .550 and flow ginormous in the low lift...

So what do you guys get?
