"What I want to know is, is why a company that has been building engines for such a very long time is having these issues?How come they are not coming forward with helpful information to assist the owners of these defective engines, to assist in getting them repaired correctly. I went to the Kohler web site and left an email and according to them, they have no knowledge of any head gasket problems. "

I don't think anyone on this forum would have access to information that would tell you why Kohler is having those problems. We could guess but that is about it. Rather than sending an email why don't you call Kohler, ask for tech support and explain the problems you have encountered. Then ask for a solution. Don't rant with open ended questions but focus on specifics. And then please share the results of your phone call.

Ked: Probably because Kohler is now being Maufactuered by different People under different Specifications !
