Thanks lads, water leak on the return now sorted thanks to 2 new copper washers.

However, having moved the car under it's own power and a little spin, it has a misfire and smokes from the exhaust under revs. Removed the plugs and they are wet with oil. Could this be valve stem oil seals? Piston rings?

Have a spare head so may put that on and see what happens?!
