Okay, so I was not able to work it out with the seller. The best I could get was an offer for a refund but not on the return shipping, so I guess I'll keep it and try to fix it.
The first head came from Asbet Nercissian, aka Pioneer556, in CA. It's been reposted on eBay for even more than he wanted the first time, which is just nuts.
The second head that I'm keeping came from Frankie Williams, aka Zperformanceracing, in NC. Looking like $200 to get it to be as described, so it will cost what the first one did in the end. Still on financial budget.
But I do have some good news: I got the block paint from Mike!
