Trimming a valve cover gasket?

Personally I would run the blue rubber gaskets that the valve covers come with originally. JMO

That’s what I had and they kept leaking.

If you cut the cork gasket you will expose the shim core which can allow oil inside the gasket and eventually cause leaks. I guess you can seal the cut corners with RTV. I have not seen SBC valve cover gaskets with such thick corners. Generally, I use steel core rubber valve cover gaskets instead of cork.

It’s already exposed but I believe it’s rigid not just flat and glued in between.

Well you already have them, I would use the Dremel with a fine grit sanding band and give it a try.

Ya that was my plan. I was just seeing if anyone else had encountered this before
