Ok, but that can be done with the front impact structure in place. But you have less room then obviously.
most difficult part is getting the vanos off and out past the structure. But I always remove the engine mounts and have the engine rest with the sump on the lower subframe (on a thin rubber mat), so the engine sits ~1" lower and the vanos can clear the substructure.

Why replace the head gasket?
You had a failure?
That's pretty rare on these engines, normally they can run like 500k miles or so...they are bombproof except for some small niggles that can be solved nowadays for cheap (loose aftermarket vanos rings, aftermarket disa flap repair kit etc).
