I read on another website where he put 1200 grit compound paste on the head and moved it in a figure-8 over a flat steel surface. He claimed the end result was perfectly straight and near mirror finish. Is that overkill?

It sounds like you have a stock short block. What do you hope to gain by improving your quench? I understand how it works but are you expecting to significantly improve your ET by doing this?

I doubt you will even feel the difference.

Where did you buy the Halomar?

Do you daily drive on your copper head gaskets?

Thanks

You don't really see it at the store. I bought it on line at Sheid Diesel http://www.scheiddiesel.com/Valco.htm- scroll to the bottom of the page. I used the aerosol spray. They also sell the chemical to get it off cause nothing else dissolves it. Other guys have used Coppercoat, saying that has Hylomar in it, but I went with this. I do use Coppercoat for a lot of other stuff, and it works very well, but I have heard mixed reactions from using it on head gaskets.
