Those thread depths will vary. You will need to look at each one individually....

Response to oil plugs on BBM block

Take a pair of calipers, measure the length of the plug, then compare it to how far it goes in. With a pen light you will be able to look down the hole and see where the oil feeds from.

The biggest issue that I've found is the big plug on the front of the block that is the end of the main galley that runs the length of the block. I typically have to fish-mouth the plug, or put it in a lathe and shorten it considerably....otherwise it will really block the feed.
