I have just completed this task myself. In order to get the two to fit, you need to grind on the Offy. You will find that you will need to gring both the front and rear to gain enough clearance.

I used a simple grinding wheel on my drill. This is a slow process so I was sure not to take off too much material too quickly.

The best way to desciribe how much material needs to be removed, on the under side of the intake there are two indented areas. You need to grind down to the lowest point of these indentations.

If you would like pictures please email me.
