Hey, i need a quick answer from all the pros out there. I just got my cylinder back from Eric Gorr today (WOO HOO!!!!!!!!, post pictures soon) and already opened the gasket kit i bought before hand and on a piece of paper it said putting some grease on the o-rings. I would look but my dad through the piece of paper away. Does it matter what kind of grease you use? And when you install the rigns make sure the "N" side is up right? as you can tell this is my first real top end. Thxs for the help :debil:
