cometic head gasket issue

I use the Mr. Gasket MLS head gskets on my 340 and they leaked/seeped water for race weekend and sealed up fine. It is common for MLS gaskets to seep water for a bit. Adam, SCE now makes a copper head gasket that does not require O rings to seal. I had to go the the MLS because of my 14:1 compression. When I built the motor I ran the "standard" Mr. Gasket high performance head gasket and blew out all 8 cylinders after two races and and you want to talk about a water leak. I have season and a half on the MLS's now and are working flawlessly after the seeping stopped.
