do you mean valve cover gasket? remove the air cleaner. remove the bolts from the valve cover, remove old gasket, clean valve cover with parts cleaner or degreaser (rinse after) put new gasket, retighten screws alternating till snug but not far to tight. make sure you have the correct gasket, alot of places dont stock them and will need to order them.

Depends on where you live. This is a major repair and is expensive. I would guess from $300 at a minimum, if nothing needs replacing except the gasket. If the head is cracked or wrapped, then it will cost more.
The install is the same as a muffler. A muffler shop can do it cheaper than anyone else.
