Classic Head Problems

[J.Sims]

Looking for some advice.

In 2010 I encountered one of the known issues with 6.0 (blown head gasket). While the engine was disassembled, upgrades were put in. (ERG delete kit, ARP head bolts, oil cooler & high volume oil pump installed) I have also installed the AFE stage 2 cold air intake and SCT programmer.

One week ago, I found out that both heads are cracked. I have heard that this problem will not go away, even if the heads are brand new from Ford.

Is this true?

Thanks

Not to my knowledge, I have not heard that at all. The 6.0 has been beaten with a stick pretty badly for it's fair share of issues but with proper maintenance and upkeep and it is a solid engine.
My honest opinion: it is NOT the engine to tune for many reasons the main two are it's size and the fact it has only 4 head bolts per cylinder.
The problem with it's size is heat, look at the size of even the exhaust valves. The combustion has much better flow dynamics with the 4 valve per cyinder design but the exhaust valves can't take the heat from the additional heat a hot tune produces.
I did cylinder head work for 7 years I have seen all different head designs beleive me.

If you have it tuned and push it then I would say yes the heads are going to be at risk of being damaged from heat and cracking will always be a possibility.
