Some come with 2 new bolts. You must use those in the top 2 holes. Make sure to put a sealer on the threads of all the bolts to keep oil from wicking up them.
Only the 4 center bolts need RTV, the rest of the bolts don't see oil or coolant.
@ OP: i used Aviation Form-a-gasket on both sides of my water pump gasket, and grey RTV for the 4 center bolts. Compare your old 4 center bolts to the 4 new ones, if the new ones are a different size, use the new bolts. You can also use the bolts to guide the pump in to place on the engine, just stick 2 bolts through the pump and get them started, then just push the pump against the engine.
Keep track of your bolts, you have the 4 center bolts which are the most critical to get right, but i think the others might vary in length too.
Biggest warning: USE A TORQUE WRENCH AND BE GENTLE. If you over tighten the 4 center bolts by just a little bit, the threaded retaining nut on the inside of the timing cover will snap off, and you have a chunk of metal inside your engine. When the wrench clicks, do NOT add "a little extra" torque after the click.
