J Heads for Rebuild

Got a set of J heads in need of a rebuild, well they MIGHT work ok as is but no idea. The valves don't look burned and the valve springs have the dampers inside. No idea on mileage but looks worn. Heads may have been rebuilt in the past.

The casting numbers do not match. Both are J heads but one is 915's and the other is 587's--I think, see pictures.

Located in S.E. Michigan and pick up in person is welcomed. Otherwise shipping is $, like $60 a head.

Will sell one head but it be $80 or $120 for both. As for my Canada friends hmm, for the sale of both heads I would take these in to Windsor Canada and ship it from there, still I guess you be looking at $75 a head to ship.

These have not been broken down by me and no idea on cracks, none seen. Was told they were off my 1973 340 motor and everything was ok, I know my short block was fine. As is, no refunds.
