If you determine that you don’t have the room to remove camshaft then you can just remove the radiator.
You will then need to get a length of 1” steel tube about a metre long and weld another 2” long tube on to the end perpendicular to the original tube,create a slot in the short tube so that you can bolt it on to your camshaft,as an extension,you will then be able to remove the cam through the front of the body.
I have done it myself in the past by this method.
Dimensions are only approximate,it’s what ever works for your situation.
There’s a gasket kit available for this procedure so that you don’t need to remove the sump,just remember to cover the sump opening once everything is removed so as to not drop anything into sump.
