i do not know what is so hard to believe...this is High HP racing... CHIT breaks...After all its Just metal anyway you spread it.....thats just part of it......before i could be dis-mayed i would have to know just how many failures these heads have had in this particular area.....otherwise its nothing unusal to see stuff break and come apart.....
My opinion
