I rode a 900 Ironhead for years,in most every state of tune from stock to 5/8" stroker with 13.5/1 cr 1&15/16 intakes buttons in the 2 ring pistons ect. And I was wondering why you want to change the rocker ratios when there are plenty of cams aviable.
I found the best street performance with lots of stroke, heavy wheels, close to stock bore, mild cams (PB+),Large open pipes slightly longer than R pipes, 10.5/1 CR and XLR valves. It was much faster with the 13.5/1 cr,2 ring Dykes pistons milled for teflon buttons and fitted at .030" clearance, but the engine life was rather short.

I've seen severall of these engines that were relieved and never saw or even heard of pinion shaft trouble. If that is what you want ( I never found the radical hi lift cams to do anything but make it sound Bad and be harder to ride a little extra stroke worked better for me) I think I'd go ahead and relieve it.
So what gives? are you proposing to shorten the pushrod side of the rocker arm?
(I'm assuming that the pivot point can't be moved).
