91 XLT head issues

[pankodog]

After experiencing a brief overheat and exaust steam I replaced both head gasgets. The problem was obviously in #4 cylinder. I dressed up both heads checked for warpage, found no cracks that I could see. Replaced heads with no success, if any thing it's worse. Internal crack? Got Imput? I'm just about to order new heads. What do you think?

...head gaskets and micro-cracked heads are common...you could do a search for head gaskets on here...
