Ermmm.... no, not kidding. The thing that takes the longest is the rocker cover and its 300 or so bolts. However, with a power impact wrench it can be a lot faster.....
. No need to lock camshafts, or support the engine properly. Stanley knife to cut the belt... etc.
If it is was my car, I would take a lot longer. I will have to check and make sure that the head gasket is fine and with a bit of luck it will be in good nick. So see how you get on and if you want it, I can try to get it next weekend.
