Thread: Valve covers for BBC with roller rockers and stud girdle and vents

Thanks Pat. Although this is going in a street car, I do plan on taking it to the drags and in general terrorizing my town. I had a custom ground solid roller cam made for it with .736" lift intake/.740" exhaust, and my machinist suggested a stud girdle. This will not always be in my car, it will likely end up in a boat or another GM car.
