Edelbrock heads

I agree that anything OOTB needs to be checked. I have 150 passes on my OOTB SB edelbrocks and they have performed well but I did find some issues which were corrected like spring installed heights, metal shavings,etc. I wish I had done a valve job on them. Now that they are off the engine that is what I plan to do. Overall they are a good product and I am very happy with them.
