Answer 1

no,,you don't need any type of sealant on it,,i own a repair shop,,and have done a few of these,,the one thing you need to do though is have the head checked to make sure it doesn't have slight warp in the middle of it,,this will cause it not to seal back up good,,and it will blow another head gasket on you,,also if it was run hot,,you might want to replace the head bolts on it,,they will stretch out if they have been hot,,and its not a good idea to re-use them again it may cause a lot of problems for you down the road,,i have done a few of these,,and so far all have come out OK,,good luck with this,,i hope it helps.

Not for installing the head itself, but you still want to get some for applying to the intake gaskets and valve cover gaskets when you put the engine back together. This is also the time to replace all the rubber hoses in and around the engine, no use having hoses disable you now that you have did a major job on your engine... Not a good thing to reuse old rubber, especially if you had to detatch it doing this job. Be careful this time of year with all your plastic goodies under the hood as well, the cold air makes stuff like that very brittle and unforgiving...

NO! do not use gasket sealer. There is one specifically for head gaskets called "Hylomar" (In australia) apart from that you must not use anything. Make sure that the head and block surfaces are PERFECTLY clean. Use buff pads to get the old gasket off and use thinners or similar to remove all traces of grease. The new head gasket will have metal rings around the sylinders, if it doesn't, I wouldn't use it.
