1969 3919840 Big Block Square Port Heads
 

I have a nice stock set of 3919840 heads complete dated C-25-9 and E-5-9 that are factory specs with the stock size valves and no porting or milling. The heads still have the flashing in the bowls and would make a great set for a pro stock or restoration project. $1250 for the set and can be reached at 330-770-2517 if interested.
