This:
is what GM calls for during a rebuild.
Kinda pricey, so that's where my suggestion comes into play for a good solid alternative.
Use what you want to, I merely did the step by step write up cause many were using the molly lube on both ends of the bolts and wondering why they were leaking.
Also, some were using Teflon paste, that was only rated up to 100 some degrees, for your common house hold plumbing repairs. Your engine operates a little hotter than that...so once it reaches that temp. the Paste turns soft again, and allows leak by. Then you have coolant leaking out side the engine, as well as in.
Just saving people headaches, Heads are one job I prefer to do right the first time was my whole reasoning behind it.
