well, gonna go with iron heads and gonna go ahead and replace the head bolts with new ones. could someone give me a link to the right ones. seen a couple different ones and just want to make sure i get the correct ones. thanks

 

Use the rockauto catalog for an '01 5.9L and there's a tab for Cylinder Head Bolts. That's where I ordered my set from.
