This way you’ll be bypassing the stud oiling (that you’re not getting anyway because of the cam) and using the superior pushrod oiling of the rockers like on high-performance 1964 engines and subsequently all 1965 and later engines.
Early Super Duty engines also had pushrod oiled rockers.

Hi B-man
One more question. So I will be basically be upgrading my 1964 - 389 to be like a 1965 - 389 correct. The push rods existing measure at 8.6875
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.
