Spent some time welding up the "extra" holes on the 73 only valve covers so they fit the 403 heads properly.

Have to go get some more sanding cones to get into the center bolt hole and smoooooooooth it out

They are a neat cover, glad my last 350 was a 73. Mine look awesome with the Oldsmobile painted red with rocket symbols painted on. Nice weld job.

Make sure you get the factory style grommets. I got mine from Rocket Racing, they worked especially nice on my aluminum Edelbrock covers due to the grommets having baffles and my covers did not.
