Some of the reconditioned cylinder blocks I've seen have the inside of the valve chest painted with a special paint. I suspect this has been used to seal any traces of blast medium left in there.
Quite a lot of hot rodders paint the inside of an engine, supposedly to make the oil return to the sump quicker.
