Denny,
Here is the photo of the page and the section numbers for your reference. You will notice it calls for a 45 Deg =/-10 setting to miss the valve cover vents. Also Denny the W-1 issue if you look at the next two pictures I posted to my webshots show the indent on the bottom for clearance. This air cleaner did have about an 1/8" clearance for the W-1 on my 216.
