Head Gasket

<< < (2/2)

Hogwylde:
I believe it's raised side up.  And it SHOULD make a difference.  Why you ask?  Take a look at the holes for the coolant to flow up and around the head.....the holes on one side are a different size than the other side.  I'd bet good money they are that way to direct the coolant around the head and cylinder in the proper manner.  Exactly what way that is, I don't know.....I've had to ask the "Which is UP" question before too.

I like using spray on Permatex Copper head gasket.  Just in case your head/cylinder is not perfectly flat, is should make a perfect seal.

Rick:
I agree, no sealant, especially RTV.  However, I have had occassion when a head gasket would not seal.  I taped 600 grit sand paper to a piece of glass and gently surfaced the head in a circular motion.  Removed the studs and did the same for the jug.  On installation, I used spay on copper gasket (available at many fine auto parts stores), and this is the ONLY sealant I would ever use on a head gasket, but the preferred method is no sealant.

Good luck

Rick
