I did verify. Twice. I suspect the cracks have been there since I bought the heads. Im wondering if they relaxed enough to pass the pressure test and when torqued down the crack opened up again. Either way, I think it’s junk.
Maybe they could have been closed up enough to pass a pressure test but I doubt it. If you didn’t do the PT yourself you can’t be sure how it was done. I’ve seen some pretty shitty techniques for pressure testing.
On top of that, they should have been magnafluxed first. I never pressure test iron first. In fact, I very rarely PT iron. I only do it if I find something I can’t determine exactly what it is.
I don’t have any single castings left, but I’ll make a call today and see what I can find. I doubt it will be a late model casting though.
