No oil to rockers but have oil to lifters what rmp to flow shafts with all new stuff

Ok, I'm new getting into this thread.

The rockers are oiled through the #2 and #4 cam bearings up through the head.

Did anyone verify that the cam bearing holes lined up properly before you assembled the engine? This can be done by straightening an old wire coat hanger and sticking it down the oil passage in the block that goes to the head and look for the wire coming through the cam tunnel (without the cam installed).

When the holes are not perfectly lined up, they call that "winked". We would allow up to 50% of a hole to be "winked" before repacing cam bearings on the block machine lines that I worked on.

Another check may be to remove the rocker shafts and prime the pump with a priming shaft to see if oil is getting up to the shaft. If it is, then you problem is somewhere in the rocker shaft/rocker arm assembly. If it is not, then I would suspect it is in the cam bearings that feed to the rocker arms. You may have to rotate the crank while priming the pump as sometimes the oil holes in the crank that feed to the cam tunnel may need to be lined up with the hole in the top of the bearing tunnel where the oil feed hole goes up to the cam tunnel. Since your engine is already assembled, you may want to start with this test first.

ALWAYS VERIFY YOUR OIL FEED HOLES ARE NOT BLOCKED WITH A WIRE COAT HANGER BEFORE ASSEMBLING THE ENGINE!!! Check all the holes in the top of the main bearings of the block, and the holes to the heads that feed the rocker arms. This advice is a little late for you, but intended for anyone else out there that will be building an engine in the future.
