I have no experience of the 'modern' head gaskets. However, I remember that, some little while ago, there was difficulty with head gaskets for the high compression head ( '36 on). My car came with an unused NOS 'Payen' head gasket which I used when I had the engine to bits the first time, as the gasket that I removed made of was some sort of Bakelite material! The second time I had the block off, I reused this gasket and, so far (and slightly shy of 1000 miles) I have had no problems.
