my mechanic says $800 to replace all 6 freeze plugs and manifold gasket high? on 1997 Jeep Cherokee

he says it is like a 6 hr job?

Asked by for the 1997 Jeep Cherokee
My labor guide say 4.2 hours labor to replace the intake manifold gasket or exhaust manifold gasket. Freeze plugs are often difficult to axcess power steering pump, alternator air conditioning compressor, any thing that is in the way needs to be removed ,price is probably fair.
ok, thanks man....seems like everything on the jeep is hard to get to when repairs are needed..heater core was same thing with the jeep...
