I’ve installed hundreds of pumps I think, every pump I’ve ever installed is set the same, scribe mark to scribble mark, same way they come from the factory, this is only a problem for pumps rebuilt by companies that did the rebuild wrong, this is why its important to get The correct pump.NO you cannot use the casting position as a timing reference, every pump is different, that is why it has a timing mark!
When the scribe is missing on the timing cover, before the pump is removed, put a scribe mark opposite the pumps scribe mark…set new pump at scribe marks.
