Thanks I will have a look.

Just noticed a massive amount of heat coming from the log manifold and heating everything up really quickly. I have just had the manifold
repaired and all the heat wrap taken off as it contributed to it initially cracking. Previously - with all the heat wrap on there was very little
heat under the hood. I noticed the manifold really toasting the side of the engine block.

Maybe this is the issue ?

Since you're in the UK why not Zircotec the exhaust manifold?

Then move on to check if the fans are working, and make sure the cooling system is burped of all air, those would be the two remaining causes, assuming the water pump is working as intended (they rarely fail).
