Don't most pushrods transfer oil to the top of the motor? Doesn't seem they would be lacking in lubrication. They probably would need to be three piece with the ends of a different material. Ti valves have steel (i believe they are steel) lash caps where the rocker arms ride.

Pushrod weight isn't as big of a deal that was once thought years ago. Look at an engine that turns 10K it has tree trunks in it. Most of the valve train weight that matters is after the fulcrum point of the rocker.

Reduce the weight of the valve train parts and keep the revs down to 6,800 and you can reduce the strength of the valve springs. That will allow a thinner pushrod without deflection.
