I had one replaced on my 4 cylinder dodge shadow. Cost about $500 I'm pretty sure.
The labor is what gets you. They basically have to tear the top of the engine down. The gasket,
at least for my car, was like $50. Of course, I had the coolant changed, a new thermostat, and
the timing belt changed at the same time. That added about $60 to the bill, since they already had to remove
most of these parts anyhow.
StandardCell- I'ld say if a garage wants $1200 for a 4-cylinder head gasket replacement, somebody is getting screwed??...
Unless the Quad4 is way more complex than I think.
