Why not?
Use the front sprocket wheel tools with the 2.5 horseshoes fitted to hold the inlet camshaft, then you can undo the sprocket wheel.
Use the rear holding tool whilst loosening the rear sprocket bolts.
As Stefan says, do not hold one end of the camshaft whilst releasing a bolt at the other end.

LGC106860 - exactly the same as the replacement heads!
So do I need to touch the replacement camshafts?
I don't know what LGC 106860 is but it is not a reliable part number! I haven't been able to find it in a parts listing for any KV6 variant.

I don't understand why you're not transferring your original cam carriers onto the replacement cylinder heads. That would remove all uncertainty.
