        I would add that to this that you probably do not want
the nice milled surface. I did this and 'roughed' up the sealing
edge with 000 steel wool. I had to pull the head off a few months
latter because it came to be with a crack between the intake
runners and was leaking coolant from said crack. When I pulled the
head off I found that the JBWeld held tightly in places and not
so tightly in others (actually came up with the black sealant).
The areas it came up in where still somewhat shiny underneath -
I didn't give the JBWeld enough surface to bit into I believe.
In most of the areas, I couldn't get the JBWeld off with the platic
putty scraper I was using...
