A rapidly increasing oil leak from the back of the left hand side head gasket along with worn valve guide seals on Six 3 meant it was time to pull the heads and put things right.
I thought I would post the progress and steps up here for those who are interested (and because Styria nagged me
)
Just getting started, throttle valve and injection pump linkage removed along with intake manifold join and cold start valves fuel supply

Left hand intake manifold and fuel lines from the injection pump to the injectors removed, the first of many components that come off, and go back on, one way and one way only, the part has to be manovered just the right way to clear other components

Right hand intake manifold and injection pump out of the way

Next Job is the suspension air compressor and coupled power steering pump removal, tight access as always

Then I removed the main coolant lines from the thermostat housing to each head, the hoses will be replaced as a matter of course as they look to have seen better days, the kinked hose you see is a bypass for the throttle body heater added as a retro fit to 6.3's when they were serviced to avoid the throttle valve icing up in cold conditions, I believe it was a factory recall.
Of course a cool dense air intake produces more horsepower so I bypassed the hot water feed![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

I documented the valve timing positions for reassembly
