I was talking to my brother last weekend and he suggested cleaning between the valves with a scuff pad to check for cracks before paying to have the heads magnufluxed, so I decided to try that tonight. Guess what? That's right I found a crack, but only in one chamber on one head. So is it worth getting it fixed or do I have to find a different core for that one now? No longer taking $h!t from anyone!

Unless it is some sort of race engine, just have them cleaned up and run them. If you are paranoid, then your only option is to buy new, because any used ones you find will be the same.
