As you all have probably seen, I like to experiment and perform my own research on different products. Then I like to pass the information on to others.

Here is one product that I have used and I am very impressed with.

Copper Head Gaskets for Harley twin cam engines. I have had quite a few multi-layer head gasket fail on some very radical engines with high compression and high cylinder pressures. My theory is, that if they work well on radical engines, then they should work even better on normal engine builds. Since I have started using the copper head gaskets. I haven't had any failures.
I have also noticed that multi-layer gaskets seem to have oil seepage after quite a few miles are put on them. Copper gaskets are installed with a copper sealer which eliminates oil seepage.

I have worked out a very good deal with the copper gasket manufacturer where they can be purchased for about the same price as a high quality multi-layer gasket.
