Hey guys, a couple more last minute questions about this timing chain (I just want to make sure its done correctly! - Do I need New Cam/crank sprockets or will the old ones be fine - Do I need a new cam bolt - What size is the cam bolt - It says to tighten down the cam bolt to 74 lbs, then an additional 90 degrees... Does that mean tighten to 74 then tighten further (so basically 110 pounds roughly?) You guys are awesome...thanks!
