I received my pushrods from Smith Brothers, and they are 9.200" long .083 wall thickness, and 5/16 solid steel ball ends. Hollow, but no oil flow.
The adjuster has a hole in the cup to get oil to the ball.
Started up, and have 15psi more oil pressure cold, and about the same at Idle. Startup oil pressure is right at 70psi, and the engine idles MUCH smoother going from 1.6 to the 1.5 with roller tips and bushed rockers.
