Valve Lash

I rotate motor and start at number one then number three and so forth on the same side so you do not get confused.....when the intake valve opens then closes you are coming to tdc for that cylinder...rotate it a little farther so both valves are on the small side of the cam lobe...set both the intake and exhaust...zero...1/8th of turn to 1/2 turn depends on whom you bought the lifters and cam from....Comp recommends zero to 1/8th of a turn past zero...
