Cieaning up Edelbrock Aluminum heads?

I agree because things like how well the valve is sealing and the valve run out most can’t check. Other things like, if the surface is flat and true, valve stem height is right and equal and the springs installed height is correct or needs a shimming, a bunch here can do it or most of it.

If there’s any doubt, send it in to be sure. If not just for the piece of mind.

The worst thing I ever had from Edelbrock was some spring shimming had to be done. NO big whoop. You just need one of these below.
