John,
First, thanks for the offer, but, being shortsighted and having just finished reassembly, I'm not ready to jump in for a set of the copper rocker-box gaskets. Also, I've built a "CJ1" (ChaterleaJohn) shock-absorbing head steady that I'm trying in hope of reducing leaks. I know there has been talk here in the past about the copper gaskets, but I'm a bit confused. Why are they more leak-free than regular gaskets and sealant? I think you will have plenty of takers.
