Anyone ever have any problems getting the intake over the alignment rings on a 216? My rings look true, yet it just won't quite go. The rings fit both sides fine, very firmly, but they fit. I have tapered my intake ports VERY slightly by removing the hard edge. Next I plan to enlarge the end exhaust bolt hole slightly to give me a little room to move. It is so close, but just won't slip over on one end. To make matters harder, it is in a COE, so the arms get tired fast trying to align it. Any tricks? Thank you's to all in advance.
