About the only problem I have heard of with the pre powerstroke 7.3 na idi's is popping head gaskets above 10psi boost, or 15psi boost with arp head studs or 20 psi boost with studs and girdle.
One thing I always loved about the 6.2's was the cooling system burp valve, talk about something every friggin motor should have.
