400 Block

Hey guys, I have a sbc 400 block with deck plugs, oil galley plugs, but what i find interesting is the steam holes have appeared to be welded up and then the block was decked. Have any of you ever done or seen this? Why would you go thru the trouble of doing this? My guess is for strength, but I cant imagine it would make a significant amount of differance. Also, why are the oil galley holes plugged up? Maybe keep the lifters supplied with oil? Is either of these things a good or bad practice? And why? Just trying to learn something new. Any insight is appreciated! Thanks....
