Is the valley area, where the visible red coolant is likely to pool, accessible to be seen via the use of an inspection camera?

Is there access for the camera probe at the rear between the firewall and the back of the upper manifold?

(I am still in the process of trying to find a suitable LS460 near enough for me to look at - there are not many for sale near me)
