Well that’s the best I can do on this set of heads.

Something I thought of that I should add is this is the first set of small block Edelbrock heads I’ve done with Manley Valves. Customer has a hook up on these and had them drop shipped to my shop. I didn’t test them to compare them them to the Liberty Pros or Ferreas I usually use. They did come with a beautiful 30 degree backcut so they saved me some time.
