Cork versus rubber for valve cover gaskets
Any opinions & experience on using cork versus rubber valve cover gaskets on GM 307 cu in V8 engines? Or use neither and replace with silicone gasket maker?

I have a cousin who owned a few shops before he retired and he preferred cork.
Gasket maker works fine but it takes more effort.

Back in the day, when I spent almost as much time under the hood, as I did behind the wheel. I used rubber valve cover gaskets. You could use them more then once, and it seemed like I was always adjusting my lifters. Then some one came out with screw in studs and they didn't need to be adjusted as much. Then I went with anti-pump up lifters, and stop adjusting all together.

Same here as what Edward said. Also found out that rubber didn't seem to work as well with stamped steel covers, OK with cast aluminum...prob do to flexing and such.
