Oil pan questions

Hi everybody:

I was just wondering if it matters much if you have a baffled oil pan or not and are these after market ones as good as the factory ones. Some of them are pretty cheap price wise. I don't really want to take the pan off of the old 318 and use it for the 340 witch doesn't have one yet. Besides it looks like someone did the old put the jack under the engine bit at one time.
