Yes, that should be entirely possible, though depending on why the pistons are seized you may have damage that would make the head worthless. A massive amount of rust being one such problem. Hopefully the valvetrain is in better shape than the pistons.Cheers, I’m doing a full rebuild as it is seized. A quick question though, is it possible to take the head off even with seized pistons?
Thanks, I’ve now removed the head. The pistons had thick (half inch) of grime on them and the valve train is badly corroded as well.Yes, that should be entirely possible, though depending on why the pistons are seized you may have damage that would make the head worthless.

If you're tearing the entire engine down for a rebuild, including splitting the cases, then you don't have to worry about saving the long cam chain.
Cheers, that a job for the weekend!!Start with some sort of rust penetrant, depending on how stuck they are. Make sure the stem is free from rust etc before trying to push them through the guide so you dont score them up. If they are really stuck you may just have to consider the valves sacrificial and tap them out or work them back and forth with a hammer of some sort in which case they will definitely be junk. If valves are rusted in they are pretty much junk anyway as well as the guides.
