Can I have a few opinions on these cracks between the centre pots. Block has just come back from the machine shop, bore size is 3.75. Worried that the cracks will continue on into the cylinder wall. Do I have a good base for a glass top coffee table or is it still useable for the street.

Thanks Peter
