Help cam problem in a 440

Josh,
BBD pushrods dont oil through the pushrods they oil through the block just as the early small blocks do, sounds like cheap lifters to me, make sure that the oil holes aren't blocked in the heads as this will cause the same problem and burn up alot of parts in the heads and cam area. Are the heads getting plenty of oil? This will be a tell tail sign, but something to check just some thoughts, let us know what you find.
