As long as the block and head surface are both flat and have a good surface to them, you should be fine.

I have reused cometic MLS gaskets before when i was in a pinch. I have done it two different ways. The first time 50% of the black coating was gone, so i painted it with a semi gloss black paint. Let it dry and put them back on, sealed up and ran them for a while. (was in a hurry to make a race) I have also used the copper coat. I would recommend the copper coat spray. I simply make sure the gaskets are good clean and dry. Then spray them down with copper coat, let it dry till it is barely tacky and reinstall. They actually seal up so well this way its a pain to remove the heads, gasket, and copper coat the next time you pull the heads.

I've never reused a Cometic that didn't leak the second time around.

Cometics are good for getting different thickness gaskets, but I do not recommend re-using any head gasket. Not even the ones that claim to be reusable. Just my 2 cents..

See yours are a little worse than mine..the black coating is fully intace except for a few small spots around the Cylinder Ring, and they are tiny.

I'll spray them and torque the heads a little tighter..lol.

Or just spend $80 at your local parts store for some new MLS gaskets and not risk having to pull the heads again?

There's an old saying - "There's always time to do it twice, but never enough time to do it right the first time"

this will also drop the compression by .4...something i am not willing to give up...i just got new gaskets TSP has them in stock and will get them to you in a few days...

Guess i got an expensive mock up set now
