Edelbrock Head Quality

Just to follow up on this: I did some additonal measurments and felt the porosity was too severe around the sealing ring for the gasket. I emailed Edelbrock Tech Support and showed them photos of my heads. They felt that the porosity should not have made it through their quality control and requested I call their warranty department. The guy I spoke with at warranty was very nice, understood what I was talking about and gave me some guidance on how to proceed to get results fast. He suggested I return the heads to Summit and ask for an exchange. Summit got me new heads without question. The heads I got as replacements have no porosity.
