(11-25-2015, 05:08 PM)barrote sorry to interrupt , but cracks does not have to do with vibes....
those holes in the precup are too wide, they are not consistente with what people is doing in here (europe) usually we d open them 25% max , my experience is in 4 valve engines and usually what works best is diff hole size , with out never exceed the 25% the botom hole stays 1.75 and the others u have them in the 25% band, i used 2.50 and 3.00 mm the only thing i gain from using the 3.0mm was noise and vibes.
my head is still toguether but i would bet vibes are killing the head.
good luck with it.
