Quote: In all the threads on the Stealth heads, I have never seen any one talk about how much the head expands with heat I had a set of there roller rockers and set the valve lash on the tight side like you would on steel heads, ended up tearing the bock apart for 3 rockers destructed we had to set them with a inch torque bar
That had nothing to do with the head expansion , more than one person has lost engines because of those rockers coming apart .
Maybe but..... The expansion or the quality of the metal used in both or either the head or the rocker is suspect plus I had imprfections in the casting too
