Thin metal head gasket

When my son and I opened up his 70 350HP 440 it had a set of very thin head gaskets on it. There didnt seem to be any problems at all with them when we opened it. They were stock for sure, but are they still avaiable and good? I know that they will help to raise the compression and the newer thicker ones will ower it.
I am sure that he is going to use the 440 source heads too. I have read here that some of you guys dont like them and that their head gaskets NEEDED to be used with them. But thats what he wants. Not for racing, but everyone knows that it will be pushed at times.
