before blasting, the water jacket holes on the sides of the heads were very evident, as well as the cavitation [?] damage around the cooling ports.
they were super filthy from laying where ever they were stored, and the combustion chambers were black from carbon.
i figured there would be no real use in trying to save them, so in blasting, it would be the quickest means to clean them up.
i used the google to try to find out more about them, [using the casting numbers] but other than saying they were for an early flat head, nothing much was discovered.
i might try to find a cheap [if there is such a thing] multiple carb intake, and make a couple of brackets to bolt the intake and heads together.
this will be pretty neat beside my dual carb aluminum rambler head, and my J2 oldsmobile intake and carbs.
