yes they should work but they also won,t provide the max benefit you could get, heres crane cams version, and its popular swap on the earlier 1984-1986 vettes when your concerned about compatibility as its a boost over factory with no bad side effects

heres a bit more radical cam, that will also work ok, but as crane suggests its best when used with an adjustable fuel pressure regulator and a 3.54:1 or 3.73:1 rear gearing that helps it noticeably, as the stock rear gear is a restricting factor
