What I am finding for 65/66 - 389’s the push rods measure 8.686 a difference of 0.0015.
Does this sound right to you and would they be .0015 shorter due to the oil spurt rockers possible being slightly thicker. This is a stock motor.

Also wondering if you have any recommendations on what rockers I should purchase and from where. 7/16 bottle style with 3/8 threads
