copper sealant?

[Superbeast406]

Hears the deal, I'm putting together my motor this week. I've got the mitsu layered metal head gasket, and i've heard if you don't machine the surfaces the gasket could leak. I prepped the surfaces my self, and I was wondering if anybody has used the the permatex copper adhesive spray on this application. I know it works good on non boosted motors, but I haven't heard of anyone using it in a boosted application. Opinions are appreciated, but I'm looking for someone who has actually used it.

I use it for most engine gaskets, especially those on the head.

you decked the head and block yourself? if its perfectly straight like you say, and torque it down to spec you should be fine.
