How many miles did it have when you replace the cylinder head? And now? How did the liners look while the head was removed?
How are they coming to the conclusion that it is a head problem? -
One thing happen often the VEB piston internal nut come loose and keep the exhaust valve open and generate a low compression on that cylinder. Ben

That sucks.
However.. it's been two months since then and proving that might be hard.
It's also could be the premature valve guide wear problem that some motors had...Socal Xpress Thanks this. -
With the roker shaft removed it’s a 5 minutes job to inspect all veb piston nuts to know if they started to unscrew by themself. When a veb piston nut unscrew your valve lash will show you too tight in fact the veb piston comes taller than normal and reduce the valve lash. Do you understand me ? Ben
