Reusing GM MLS gaskets?

Are these safe to reuse? I torqued them down, but I am thinking about pulling a head to weigh my valves (want to check if I got the hollow ones.) They have been torqued, but not ran. What if the black coating around the piston/water jackets is messed up?

Any input?

You can re-use them even if they're been run. ( I don't) If you're concerned about the water jacket area you can use a little copper spray or a thin wipe of Ultra-Copper RTV.

If you pull the head, spend the $55 and get new ones. Why chance it and all the headache that goes along with a leaking head gasket over a lousy $55...

You should be fine. It would help to keep the coolant passages clean if the gaskets were cleaned before you put it back on. I don't think it'll do much if you didn't though. Why didn't you use a thinner gasket?

If not run, no issues at all. That is a lot of work to just measure a valve.

Well the motors on the stand, but after reading your other post about hollow and dual springs I don't think it really matters. Just wanted to see if I got scammed on the purchase.
