If you are running stock lifters and stock valves, you should be able to run the L31 pushrods without any problems.

Just about any other change potentially affects the pushrod length.

-Milling the heads.
-Change of pushrod cup location with respect to the cam base circle.
-Any component change that moves the height of the valve tip - longer valve, lash cap, deep valve job, etc.
