i just had and engine built and broke it in the other day. i had a small tick comeing from the valves. i adjusted the play in them and noticed that on the rocker arm itself it says 1.5. i looked on my cam card and it says i have 484 lift with 1.6 rockers. i am wondering if my engine builder is dicking me around or are they ok. i also pulled the lifters out and checked them over, the broke in very well, and seem to be working fine. i am just wondering if i need 1.6 or if the 1.5s are ok
