I used these heads on a street stock (3200lb) car for years.also ran on mod for one season because I had them.Turned around 6500 to 6800.It made good torque.You must use a thick head gasket not metal.The late model 350 gaskets from chevy work well and are only .026 thick.use them if you got em.

they work great on hobby cars if you port the snot out of them and have used the thin metal gasket with them and have heard that they work better with the smaller valves in them
