lifter boxes

I'm getting ready to change my head gaskets ( because I have one blown) Is there any benefit of drilling a hole in the lifter boxes ? I seen this done on Hot Rod Tv!

Yes, it's mentioned in the "How to build a HP LS1 / LS6 book" as well. Basically it improves oil drain-back from the lifters to the oil pan.
