Great Video Mike!
Ok, just got the block back from its acid bath! After an hour or so with the wire brush, it's looking so much better! The great news is that it looks like a good block! No cracks found on first visual inspection after brushing. Will clean some more and check the problem areas.
Next step will be to somehow pressure test the water jacket just in case there are any porous areas.
Once I'm convinced that it will hold coolant it will go back to the machine shop for a re-bore. It's a standard block at the moment 3.1875 bore. There is some pitting on a couple of cylinders, so will order pistons once the final bore is established.
Will order parallel valves and single piece guides etc. ATM I will keep the original cam, although not ideal, it's an expensive item to replace.
