Hi Guys,

A head gasket blew, so I pulled the heads apart to replace the stem seals. When I did, I noticed that on the intake side, what appears to be a copper sleeve is protruding from the value guides. I believe the head to have been rebuild at some time. I dont know for sure, because I just bought the truck. What's with these sleeves? What's the fix?

Thanks for your help! smile
