Benny, thanks for the welcome, thanks for your opinion, and thanks to
everyone else for their 2 cents. I do agree, this head is garbage. The
conclusion is that I am going to buy 2 used heads from a reputable used
parts dealer here in the Seattle area. The heads look to be in very good
condition and the price is right. After I install the working heads, it will
be time to trouble shoot the cooling system to see what went wrong!
