stainless ones i got from ebay over there in the states. pics on page 7, post 174. having looked at the pics again myself the header ports are also rectangular so i'll have to make a couple of thicker copper gaskets which will cover the port misalignment i have. you know i've watched engine masters and so many times i've heard david freiburger say ''check header fitment before you install the motor'', doh!!! :BangHead:
