Hi Paul.
Scroll down to my thread on removing the head studs.
Phil has posted some good advice for lifting the head there.
When I bought my truck 3 plugs were rusted right off but I had no problems
getting the head off.
The studs are a different story.
All the best.
Terry

Oops, just noticed Phil's posting not there any more so go to his website.

When you get the head off, light a fire on top of the piston. It will heat it and the rings and the expansion will free them from the (being frozen to)bore.
A small bit of rag and diesel is all you need. It will burn slowly with a yellow sooty flame.Let it burn for quite a while. Probably you will put the diesel in the hole, light he rag, then drop it in.
When the fire it out, add some oil before trying to turn it over.

The piston rings are probably rust welded to the cylinder walls....... amazingly strong when you consider the surface area of the ring against the cylinder wall.

I have had better luck with some mechanical force than with diesel, ATF, rust blaster, Gibbs, etc.....

Cut yourself a good sturdy piece of wood that will almost cover the whole face of the piston...... leave the diesel fuel 1/8 of an inch..... you have the bottom end open...... locate number four and hopefully it is probably half way up or down...... alternatively tap the piston from the top and tap the crank ( using a block of wood ) from below...... be patient.... it will eventually break free....... you may need to polish the cylinder wall with 600 grit emery paper soaked in fuel...... rings may need to be replaced....... has worked for me every time on old Allis Chalmers tractors that were left in the rain. Having someone to tap from the top as you tap from underneath is a God send..... don't ask your helper to do the tapping from below...... the oil drips will spoil the friendship. I have done this with the engine still in the tractor frame.....and my old WC and C are still running.

cheers

Thanks every one and I will be giving all these answers a go next week when I get back on the C8
