Re: Valvetrain issues on new engine build

With that short of a pushrod it is posible that the rocker arm is bottomed out on the rocker stud. Look at the bottom of the rocker arms to see if any material is scraped off the rocker. Also check to see if there is space between the pushrod and the guide plate near the valve spring to see if maybe the pushrod is bottoming out on the guide plate. You need to check these things out by turning the engine over and watching the pushrod throughout its travel.
