Before I put the heads back on, I sent them to my local Napa auto parts store to get them resurfaced and checked for cracks and warping. I've sent in dozens of heads and they have always come back with a shiny new surface and no cracks but this time one of the heads was cracked and they were unable to resurface either of the heads. Although it was a pain in the butt, I didn't think it was that big of a deal and had probably happened when the gasket blew.
I pulled heads from a junk Loyale with half the miles which apparently run but had a timing belt problem before it was scrapped. No blown head gaskets or motor problems as far as I could tell. Before I put them on my motor I once again sent them in to get checked and resurfaced. This time both heads were cracked.
Before I hunt down another set of heads, and have the SAME thing happen a third time, am I making some sort of mistake? Do I just have really bad luck so far? Is there some reason I shouldn't be getting them checked? Are Subaru heads naturally very very fragile?
Both Engines are EA82, my car's not turbo. The Loyale had too much missing to tell if it was turbo or not.
