Head gasket reuse question
 

I have a spare 40’s flathead I bought a few years ago, I want to mount it on an engine stand and run it, I pulled the one head off last year to check the cylinders, they look good, can I just reuse the gasket to test the motor?, do I need to coat it with anything? It has a graphite gasket on it now.

If it's surfaces are still decent, I'd use wheel bearing grease if it was mine.

With a Graphtite that wasn't leaking I definitely slap it back on.

Give it a go. What's the worst that could happen?
I reuse copper gaskets. Not tried a graphite one, but would try it for a test run. It depends on how cleanly it came off, but if any remnants are on the head or block, leave them in place. Just my hunch.
Mart.

If the gasket was copper you can reuse it many times over. If its one of them there composition type gaskets its going to be a gamble for sure if it will seal correctly.
