painting head gaskets?

I figured out my low compression problem was due to blown head gasket and not the heads. (for those of you following my problem )

I bought new head gaskets and i was told by the Kragen worker to spray paint them with aluminum paint before putting them on, is this a good idea? I asked someone else and they said they had never herd of it.

What kind of gaskets are they?

Unless they are bare copper/metal, they should go on dry. When all else fails.....follow the gasket makers instructions.

Years ago...it was common practice to spray head gaskets..they even made a copper gluey mess for the purpose (still do).

I have painted many, many sets.
Stopped about 10 years ago.......

Go by the head gasket manufacturers recomendation.....

Most modern head gaskets are installed dry. But, read the instructions!!!!!

That's what we used to do years ago with the cheap steel shim gaskets. Paint it with aluminum paint, let it dry for a while, then spray it again right before you install it. That was before they made the spray copper-coat stuff. Definitely follow the gasket manufacturer's instructions though. Make sure your block & head surfaces are not eroded at the point where the gasket failed.

Did exactly that this weekend when installing heads on the hemi for the truck. Early hemi head gaskets don't have a sealed coating on them and require a coat of that very same coper gooey, sticky gunk to seal properly. (As per the gasket makers directions).

Like the man said, spraying head gaskets used to be done on a routine basis, but modern technology eliminated the need to do so (providing you're using modern head gaskets).
