BB valve cover???
When did the big block engines change from the rubber pop-in oil plug in the valve cover to the twist in type?? I want to put the correct ones on my 70 GMC 402. Thanks.

I don't know when the changed but my 71 402 uses the pop in rubber one. They are without question the stock valve covers.
