How to change a head gasket?

My mainly question is... Do you have to do any adjustments on the head after removing it? because i don't want to remove it and then not be able to put it back. Can some one give me a link to a video or pictures where they show step by step on how to remove and put back on the head.How to change a head gasket?If you do not know how to do this I would suggest you don't try. Without someone there with you that does. Once the head is removed it needs to be surfaced and valves ground. This has to be done by a machine shop. The surface needs to be set down on flat ground on clean card board then sprayed down with carb spray until reinstalled. The block has to be cleaned very well and free of any contaminants. All head bolts need to be replaced with new bolts very important. When you put it back on there is a certain sequence the bolts will be tightened with a torque wrench. That sequence depends on the year make and model of the vehicle. And is very important that it be followed. Some bolts get oil some get sealant. After they are tight some require to be loosened and then calibrated to a certain degree. There is also a sequence that needs to be followed for the intake as well. Very difficult task if you don't now how to do this. This is a very costly and could cost you more to experiment on it then if you just have someone that does know how to do it right. Gasket set is usually like 120 bucks the machine work is a must and will run anywhere from 100 to 250. And if you crack the head or heads your looking at another 300 to 400 to replace them. Besides that if the car has been hydraulic looked and quit running immediately it may have damaged the engine as well. If you mess up it will cost you more to replace parts then pay someone to do it the second time around. Best bet is to spend the 500 to 1000 to have it done by a professional. This is a job that requires more than just take it apart put it back together knowledge. Hope this will help feel free to leave feedback thanks.How to change a head gasket?Get a Haynes or Chilton manual for whatever make that you are changing the head gasket on. Either way, you'll still have to scrape the old gasket off with a razor blade (carefully). You also might want to use a tap and die kit to clean out the old compound that was used to put the head bolts on with. Your book will tell you specific torque readings for you to tighten your head bolts and will tell you the specific sequence in which to tighten the bolts.How to change a head gasket?Basically you should do the same thing here as when you remove any other gasket, clean the mating surface really well. I always spray down the surface of the head with WD-40, then wipe it vigorously with a scotch brite pad. Put a rag in the cylinder to keep crap going down in there. This should get all the grease, oil, and gasket remnants off it. When reinstalling the gasket, to get a good seal you'll have to torque the head to spec.
