It sounds like you may have gotten this crankshaft already drilled and are wondering if there are detrimental effects to drilling? Based on your original post I would say there are no detrimental effects to cross drilling without grooving but there should be some benefit to lubrication of the two rods closest to the center main journal. I wouldn't worry about grooving it if you are just going to build a stock motor. I would say all upside in your case and no downside if you didn't pay extra for a mod you didn't really need. I have only a couple of thousand miles on my build but all seems fine with it. I guess I won't really know whether crossdrilling was good bad or indifferent unless I blow up the engine then tear it down and see.....
