Cracked heads and blocks.

[Forumadmin]

I have a few heads and cylinder blocks with cracks so a visit to a couple of local engine shops started a quest to find a repair process and shop to do it. The engineers at Apsley Transmissions and Classic Autos gave some useful input and warned me off a couple of local machine shops that I had used in the past (30 years ago) but have now new owners.
First some research.

Heads often go between the thin isthmus between the valves. Last year a valve seat fell out and was probably caused by such a crack. Since this head has had a lot of work done to it, saving it may be cost justifyable.

Now off to find someone who can do it and at what cost.

Any update on cracked head repair companies? (asking for a friend)

Suggest the friend contacts rl engines and reports back as I have not followed up.
