Ford Lehman 4 cyl diesel early 70’s Sabre 80hp

[cagey]

I need to do some work on Ford engine , marinised Devon or Dorset truck engine, if I take head off will I need to replace head bolts for unstretched new. Any other tips how things have changed over the 50 years since engine was built, I’m looking forward to working on an engine that was built when I was working on mini engines as a kid. It’ll be another journey,first learning on A series then new learning on modern petrol and Diesel engines and now back to basic ‘agricultural’ engines.
Where should I go to for reasonable priced 70’s Ford parts please.
Thanks
Keith

Your best bet for parts is Seahorse Power, Steve there knows these engines inside out.

Far less important to change head bolts on older engines,
I wouldn't.
