It could be, depending on the type of engine and whether or not there is further damage to the cylinder head. On an American V8 engine, you can usually get the heads refurbished for about $150-$200 each at a reputable cylinder head repair shop. Of course, this does not include the labor to remove and replace the heads on the engine.
If your engine is an older car with a large amount of mileage on it, it may not be worth repairing. If the car itself is in good shape, you may want to consider having a rebuilt engine installed in it. You'll have to weigh the cost advantages yourself.
Because of the introduction of Sintered or powdered metal (PM) seats over 20 years ago, some of the OEM manufacturers are experiencing valve seat failures on relatively new vehicles. Chrysler models with the 3.7 V6, 4.7 V8, HEMI 5.7,6.1 liter and most recently the 3.6 liter V6 introduced in 2011. Ford 1.9 and 2.0 SOHC engines in the Escort and Focus also have this issue. There are many reports and opinions why this is happening but it appears to be a manufacturing issue but in my opinion, the driving force is cost. In our shops we have been replacing PM seats with premium grade traditional seats without a single failure.

Why does an engine valve need to be removed from the cylinder head?
An engine valve normally needs to be removed from the head for a valve job, or to replace other parts related to its operation like the spring or valve guide. This is normally done when the engine has a poor seal from the valve/valve seat or oil consumption caused by the vavle guide.

How do you replace the check valve for the air suspension on a mark 8?
The Mark 8 does not have a check-valve in the air suspension system. Each air spring has a solenoid valve, which controls fill and vent of the spring. There is a fifth in the suspension compressor itself, which controls venting the system. I discovered that the seat for vent valve was corroded in my compressor, which would then leak when the system was trying to fill. This resulted in the compressor running, but the car lowering. I was able to clean the seat up for a temporary repair, but ultimately replaced the compressor.

How do you turn off the water spigot outside After closing it full water is still flowing The only way you can stop the water is by using the shutoff valves attached below the handle Help?
Sounds like you have a bad valve. It would be best to replace the valve, most last a long time, but they do wear out. It is probably a gate valve, they are not that costly and are not difficult to replace. Before you replace the valve, you might want to check the rubber washer and/or seat within the spigot handle. Sometimes the washer will tear and will allow water to flow. Seats also wear in time and won't allow the washer to seal. Washers and seals are "a dime a dozen" and certainly much cheaper to replace than a new valve - also a lots easier to replace. Borrow a home repairs book from the library or do a Google search on plumbing repairs for detailed info on how to do it.
