Eddy RPM heads: Should I be concerned about this casting defect?
So I have an update...and you guys will love this (and probably not be surprised one bit).
First of all, I just noticed this today as it's really faint. There is an "OK" mark written on the defective head:
Interesting.
Secondly, I got my 2nd head today and looked it over real good. No visible casting defects. But due to my skepticism, I didn't like the way the valve seats looked. There are tooling marks/scratches on the side walls of some of the intake ports, just past the chamfers. See the pic below, you can see it where the discolored area is. I can't even pick it up with my fingernail. Then there are a bunch of little blemishes that I can't explain. You can see those as the light spots in the pic. The other head with the defective casting was so clean on all the valve seats, it made me question it.
Thirdly, I called Edelbrock today. Seems their customer service is as good as the quality of their parts. Calling the main line, I get a woman who answers the phone "Edelbrock". I ask to speak to someone about defective parts and she says nothing, just puts me through to an automated dialing system. I punch some numbers and choose the closest option to what was given to me...tech support. Can't remember the guy's name but when I told him about the casting defect all I got was silence and then an "uh-huh". That's it. I commented about how it shouldn't have gotten through QC. Silence was the response. I go on to tell him about the other head with valve seat marks. He says it's a bare casting head and the valve seats need machined and that will all clean up. Makes sense to me, but I wanted to share here with people to get an honest opinion. Am I ok with the valve seats as best as can be seen from a pic?
Thanks everyone again for the feedback.
