Alright guys, I finaly got my engine all finished and took it out for a little bit saturday night. All went great, ran great, didnt get hot, everything was perfect. Well sunday morning I went to go drive it some more and happened to check the oil and saw the famous "Milkshake". Tonight I pulled the head and cylinder #6 looked brand new. I assume this is were the leak was but the head gasket looked fine. Im thinking the used heads I got were a little warped so I pulled the other one off and am going to have them checked out tommaro. My question is that even if they were warped wouldnt they still wear the part of the gasket were it is leaking in the cylinder? Could I have put them on wrong to cause this? I torque them down in three steps to ARP specs using ARP moly lube and start off from the center going out. Do you guys have a very detailed write up I can follow when I am installing them just to make sure I am right? What head gaskets do you guys recommend from felpro? Thanks and sorry about the long post.
