8 to 10 hrs labor to change '225' head gasket ?????

The workshop times guide books are only approximate any way....it all goes out the window when something goes pearshaped....broken studs, broken bolts, broken spark plugs, pulled threads, stripped threads, corossion where it's the worst place to have it......then theres all the cleaning....some may be easy to clean, some may be hard to clean.
How far do you want to go ?????
This is my daily driver.....head gasket had just started sweating coolant....so I put my p&p head on it.
