Yes, stock rocker arms are 1.7. Changing them to a 1.8 rocker would increase valve lift and increase duration at the valves little. Cam duration and lobe lift remain unchaged. Using 1.8 rockers would increase your lift to .590, beyond the ability of LS6 springs but still within the realm of 918s.

You need a 8mm 3/8 drive 6 pt socket to BREAK to locktite on the rocker bolts. You need something to keep the crank from turning while removing and installing the crank pulley. I use a big chain wrench. Buy it in the plumbing dept at Sears or a a plumbers supply. You'll need to add some extra chain links because it is intended to hold 4" cast iron sewer pipe not an 8" crank pulley. I made my own cam remove/install handle. Welded a 2' long steel rod to a piece of 2" square flat stock into which I drilled holes for the cam sprocket bolts and dowel locator pin. Works great. I wouldn't do this job without installing an underdrive(ASP). A double row adjustable timing set is a good idea too while you have it apart. You're only looking at $300 between the pulley and chain. Well worth it since you'll already have the motor down anyway. When your removing the pulley I use a BIG allen head cap screw in the crank bolt hole to convince the puller rod to stay centered. The cap screw forces the puller rod to be self-centering. The best puller is called Posi-Lock. They make using a 3 leg pulley a one man job. If you use one of the cheaper ones you end up feeling like you need 3 extra hands to keep the legs from flopping all over the place and oh yeah you have to get the puller rod centered and screwed in at the same time. A Posi-Lock ends all those problems.
