Then turn the crank 90 degrees, and lash whichever valves are now fully closed, turn the crank another 90 degrees and repeat, until all 8 pairs of valves are lashed. Torque the jam nuts on each roller rocker to OEM spec which is something low like 10in-lbs (<--- VERIFY THIS with HELMS) And your all done. Slap the valve cover back on and your good to go.
Be aware that you should turn the crank 180 degrees a total of FOUR times from TDC back to TDC, as there are two revolutions of the crank to one revolution of the cam and the key here is the cam placement, not the crank. For TDC, check for the marks on the middle sprocket to line up with the deck line, but most importantly be sure the marks on the cam sprockets line up, too!
Everyone should have a Helm's, so please always check first!
