Same with the rubber version. I did make sure it was attached to the cover with some 3M Spray77 glue. I was able to reuse a few times with that setup.I 've never had problems with cork rocker cover gaskets, even when i used to cover 20K miles per year come rain or shine. That said, it was critical how i fitted them first time, but once they settled, they even standed a few removals / refittings of the rocker cover without problems.
I admit though that it is easy to overtighten the rocker cover bolts and squeeze the gasket out of its position.
If you are getting leaks make sure it's the valve cover and not the O-ring in the head gasket leaking down the back of the block. Alternatively, I found it can weep if the breather hoses aren't setup onto the carbs. Just venting the hoses with a filter doesn't help.
