I ended up using the cotronics 940ht high temperature (3000 degrees). I don't have access to a torch and on the performance years web site a number of people had good results with it. It was a little pricey (about $100 for the quart size), but I have done 2 sets of Pontiac heads and could easily do another set or two. After two years of running, the adhesive has held up fine.
