As said, most of the jobs your car seems to need are fairly straight forward. Following a Haynes manual or asking on here, you would see a huge saving
For example, it will cost you £350 for a head gasket and valves to be done
If you were to do it yourself you'd have almost that much to spend on other things
I did a head gasket change and de-coked the head and lapped valves in. It because me £18 for a gasket and a few quid for lapping paste
+1.
It's the only way most of us can afford our classic car hobby.
With labour rates between around £35 an £50 per hour, and anyone working for much less might be a 'cowboy', the amount of on-going work any 50+ year old design of car will cost a small fortune.
DIY is really the only way, well it certainly is for many of us on here. That way there are several advantages:
The first is that you will know the jobs have been done right.
Secondly you will know the source and quality of the parts used.
Thirdly the labour cost is zero.
