We have been using the SCE Titan gaskets with good luck. They seem to do a good job sealing up the coolant.

SCE Pro-Copper with a little Hylomar around the water holes if you run water. The pro-copper work best with o-rings and receivers. I have never used the Titans but if they are anything like the Pro's they will work great.

Being it is oringed on the block, you have to run copper. But, we have found that with an oring, a receiver groove in the head or vice versa, keeps water leaks down to nothing. With just the wire, water leaks around all the water passages. It can't really seal becasue the copper can't take the .010 ti .015 and let the head settle flat. Basically, your setting the head on top of 4 wire surfaces! Ideally, the oring would push the copper head gasket into the receiver groove thus making a pretty much indestruckable head gasket, even better than Cometic MLS!
