Default Porting out a 85mm bbk intake to 90mm?

I have been thinking about porting my 85mm bbk intake out at the throttle body opening to fit a 90mm throttle body. Has anyone done this or thought about it? Can the bbk intake flow good enough for a good gain by going to a 90? I have smothed out the runners of the intake already.

Better check the throttle body bolt pattern. Doesn't the 85MM have three bolts? My 90MM has four bolts.
