Thommo's dead right there.
These Rocket Covers were a very close kept secret with the early holden racing fraternity way back then.
Fit one of these to your standard grey or red motor and you were guaranteed an extra 15 to 25 MPH on top of your old maximum speed with the old standard Rocker Cover.
Went like a Rocket hence the name Rocket Cover

The Rocket Covers have to be polished to achieve that top speed gain.
Non polished or pitted Rocket Covers are not much better than the standard ones.
I'm told by those "in-the-know" that its something to do with airflow through the radiator going past the polished rocket cover is where the horsepower gains are made.
Non polished/pitted ones create extra turbulence and consequential airflow restriction and hence the reduced speed.
Makes sense to me

P.S. The above is all tongue-in-cheek Bullsh#t, just in case anyone thinks its true
