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.
You may have listed the part numbers somewhere but if you repost it and where you live I know I will keep my eyes open for you. Let us know if you are open to buying a pair and it will save a little work.
