Reply to "New heads, new intake, new rockers, new pushrods - Very noisy valves and very little oil through pushrods"

Somewhat to what bosswrench said it's probably a good idea to verify that all the valve-train parts are designed to work together and are correct for that engine so enough oil is passed from the block to the lifters, to the push-rods and ultimately to the rockers. A little too much oil to the upper end in a street engine with enough drainage is harmless, not enough is.
