PROMAXX Performance Vortec 185cc Iron Cylinder Heads

2.79 out of 5 stars 14 Customer Reviews

PROMAXX Performance goes one up with their Vortec 185cc iron cylinder heads. Popular with street/strip enthusiasts and Circle Track racers, PROMAXX designed these heads to work well on 350-383 applications. They're available bare or assembled; both feature screw-in studs and large diameter spring pockets. In addition, they both accept centerbolt and perimeter bolt valve covers—and are drilled for Vortec and carbureted intake applications. Greater performance at the right price!
