Odessa heads - take a look.. Looking for input *solved

I don't see a issue fixing a crack by pinning, but I would never do it on a valve seat. That head is junk in my opinion.
I've never bought new head/refurbished heads. Always did heads my self and if they need new guides have them installed. If I found a crack, I've never repaired them. I always found another head. So working with heads that's been repaired for cracks is new to me.
