First off Comp XE grinds are noisy .

Oil path , pickup tube > oil pump > filter > passenger side main galley ... which feeds all the lifters > there is a path down to the main bearings > main bearing feed also feeds the cam bearings , #4 main feeds the #4 cam wihich hit and miss feeds the rockers > passenger side maingaley wraps around back of the block and feeds the drivers side galley.

Are your pushrods the proper length ? How much preload on the lifters ?

Is the oil path listed for a small block? I'm wondering because of the oil filter location (rear passenger side for sb, front driver side for bb). But in any case, what you're saying is that the oil flow to the lifters have nothing to do with any of the cam or main bearings?

As for the pushrods, yes we believe they are the correct length. When the top-end upgrade was originally done it had adjustable rockers and we tried every pre-load between .25 turn to 2 turns with no change in this particular tick. Obviously at .25 turn the valvetrain was more noisy overall, but the main tick never changed.

Now that we've swapped to stock rockers and pushrods it's the exact same.
