diesel head problem :/ help please

[Dervy]

on the engine that im rebuilding, iv got the head of and found that there are a couple of cracks in the combustion chambers, iv scene this before on other diesel heads at work but it wasn`t a problem. Im just a bit concerned because im going to be putting 25psi of boost into this engine and im not shore if these cracks are going to be a problem :wtf:

id get a new head especially if your putting more boost through it!! saves putting it together then it blowing!!
