The later 307 heads only have 5 bolts for the valve cover vs. the earlier olds heads having 10 bolt valve covers. The valve covers will work fine you just need to plug the unused holes.

Those covers will fit, they are 10 bolt covers that work with older heads. All you have to do is find a way to plug the holes. Use black silicone on mine for now until I eventually switch to the 5 heads.
