I have a nice set of rebuilt heads casting number 3919840 dated E-18-7 and E-23-7. The heads have no porting and have been angle milled. The heads have 2.19 intake and 1.88 exhaust manley valves with competition springs and built to stock specs. These heads were used on 427-435HP vette and 396-375HP camaro's and chevelle's for 1967 model year. They also used this casting number in 1968 and 1969 model years as well but these would be dated for a late 1967 model car. 330-770-2517 if any questions.
