Mine needed surgery after it blew a head gasket on the way back from a Derbyshire run, not my lucky weekend as I had to do a speed awareness thing last week after being clocked at 36 in a 30 limit.
A local friend with a very nice 61 PA Cresta has been round to help reset the valves and timing,
(have to admit I had to use a second Head Gasket as after thinking it was cured water was getting into the oil after starting and whilst there is no sign of such the second time round, it was only briefly started.
I hope the problem is solved , however I am awaiting a carb gasket for the Solex carb as they sent the wrong type, I just hope the head wasn't warped ,on the car that is.
