Would the valve covers from a 1990 Corvette fit on my heads. The vette valve covers are the center bolt style that are cast to look just like the plenum... the same squared off groove pattern. I'm asking because based on pictures I've seen, it looks like my valve covers have three things total coming off them and the vette only has two. Would they still work?

The person with the valve covers also has some 113 aluminum heads for sale too. I was thinking I would look into getting those too, but what would have to be changed to make them work? Would they just bolt right on in place of my stock iron heads?

Thanks,
Mike
