My home inspection of Speedmaster heads

Nor have I heard of anyone doing anything different about it. Let's be fair, people have been running OOTB Edelbrocks for a lot of years now, and no issues reported? Hmmmm……
P.S. - I just ran a plug in mine, and of course the same results...
I think on these that something should be done. That’s just to far in for my liking. Sand roll as stated or a light dressing with a Dremel and carbide bit? Or is that to aggressive? Kim
