This gave the mains priority in the oiling system and greatly increased the 427's ruggedness. This side galley casting is the sure identification of a 427 SO. I do believe, however, that some service blocks show this casting but are not drilled and use solid lifters.

Not true... If you look over on fordfecom there's several pictures of industrial/irrigation 427s that were not cross-bolted. Just saying...
