Port matching throttle body to intake
 

Okay, so tomorw on goes a 76mm mass air and a 65mm throttle body. I couldn't get a hold of an egr spacer plate so I'm planning on just honing out the stock one and bolting it up. My question is, how hard is it to port match the intake to the 65mm throttle body. I have a little experiencee with machining but I'm still not really comfortable with it. Should this be taken to a machine shop and if i can do it at home, what should be done. I mean sure i can make the opening 65mm, but how do you match it to the runners? Chances are im gonna have to take it to a machine shop and be raped out the *** for the price.
