How are they or their customers getting around that?

I had a Dart Iron Eagle tall deck (9.325"). The rails were spread and the cam raised. With a 4" stroke, 6.200" rods, the CH was 1.125". The drawback of the block was that it required a special pan, intake manifold, and adjustable slip collar distributor.
