heads on 2001 Ford F-350 Super Duty

Can the heads on a V-10 be removed with the engine in the truck?? I have been told..either the cab comes off or the engine gets pulled. Others have said yes.......can be done in the truck.

It can be done in cab. However it is tight tight tight and not easy. It goes fairly deep under the firewall with limited clearance.
