hi. if i set the lifter preload according to procedure and came to 20 ft lbs. between 1/4 and 3/4 turns of the stock rocker bolt my rockers should be set just fine right. i checked to see where the rockers were hitting the valve stems and they were hitting off centered even though i had the correct shims in place. i shouldn't need shorter pushrods if i got the preload on the lifters within 1/4-3/4 of a turn correct using shims correct. so what's the deal, why am i getting a funny marking. i am using fingernail polish, could it be that messing me up. if anybody lives close to conroe,tx and wants some beers, feel free to come on by and check this thing out. it's giving me hell.
