For those of you who have rebuilt the 6 packs what O-ring lube did you use?
We used: Super Lube 21030 Synthetic Grease (NLGI 2), 3 oz Tube: Science Lab Cleaning... (https://www.amazon.com/gp/product/B000XBH9HI/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1)
Synthetic engine assembly lube, don't build your Chevy without it. ^.^d
X2 - Another vote for Super Lube.
I don't remember the name of what I use but it is special for o ring lube installation. It is in a yellow tube.
