I found the issue (HotVWs May '06 pg.86-88). They used hose clamps and aluminum flashing (for roofing) sold at the hardware store in rolls. They wrapped a piece around the "J" tube under the head, and secured with one hose clamp in the middle. The head ran 30 deg. cooler.
The same article states that "header wrap" should not be used on street cars. When the wrap gets wet, it produces steam that rots through the steel "J" tubes in no time at all. (sorry chug_a_bug
). If your car never see's rain,or water than it's ok I guess.
