I'm going with a Skunk2 Alpha 66mm throttle body on my build. Can a P75 (b18b1) intake manifold be bored over to about 67mm?

 

Bore it to 66mm and be done. No point in making it larger

 

From everything I've read and seen, its my understanding I should go slightly larger than the throttle body for anti reversion. I was just wondering if the intake manifold is big enough to be widened to about 67mm.
