The old style watercooling heads had some paper mache around crush metal. Unfortunately, these are prone to leak if they cannot be fitted perfectly as heads do warp. I may go and shave the head, had to do that with my Cr500, but what are some tried and true other methods of creating a seal? I know some have used types of sealent, I tried Honda Bond HT unsuccessfully though, still leaked. I have heard of silver spraypaint on the head gasket as well to create a bond.
