OK, I'm getting my motor assembled and have measured my push rod length. What I need to know is if .080 wall, 5/16" diameter rods will do the job or do I need to go to 3/8" . Also most seem to have the oiling feature but my Comp steel rockers have a provision to oil the top of the push rod. The combo is Comp retro hydraulic roller lifters and a comp roller cam with .538 lift. 440 Source heads with 145lbs on the seat and 350lbs open. Street motor with a max rpm of 6K.
