I think I read you saying that Magnafluxing should be manditory before purchasing them. I agree, which is why I didn't buy them outright. If somebody has an interest in these, I can go to bat for the interested party locally and strike a deal with the seller. When I needed one of these heads that wasn't cracked, I remembered it was like trying to find hen's teeth so that's why I was kind of excited to find a pair of these around here. Chuck
