You absolutely, positively MUST measure the depth of the dowel pin holes in the head.

If its fractured around the bottom bolt holes you can pretty much bet the holes weren’t drilled deep enough.

Ive posted that here more that once. That’s what causes the fractures like that.

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.
