Hi all,

Preparing to install the LT4 Hotcam and so far have removed everything off the front, moving up top I have removed the traction control unit and have removed the driver side valve cover. Much to my dismay I have found what looks like a blown head gasket. On cylinder 7 there is the classic "chocolate milk" deposits on the rockers and the valve cover. Well just wondering what kind of head gaskets you all are using and should I get the head machined? The car only has 50K miles on it, here is a link to the pics I have taken.

sounds like a good time to do HEADS and cam. Prorac1

 

It's probably just condensation on the valve cover. It's pretty normal. Check the oil in your pan, if it's not milky then you should be fine. Also, do a compression/leak down test and check for oil in the coolant. Also remember, if you remove the heads, you should have them hardness checked as well as have them checked for warpage and their surface must be perfectly smooth before you reinstall them or you will blow a head gasket.
