Many, many years ago - I did the head gasket on my Escort Mk 2 on the drive using just a Haynes manual
Only tool I didn't have was a torque wrench - Luckily I was able to hire one from car parts shop near me (When there were independent motor factors)
Gasket blew on way to work on Friday morning - I had to be in Chester the next day - so booked day off work and changed gasket
If the Morgan is your "second car" - I'd crack on
