I have not got that far yet, but it should not need any.




You should be fine with a good 3/8" pushrod.We just finished a 605" with 7/16" Trend tapered pushrods.We checked them by putting machinist dye on them and spun them at .002 lash and found slight marking at the head/deck line.



Ssshhhhh, I am not allowed to say anything.
