Default Re: Y Block rocker shaft changes for better oiling

There is often more to the story. Ford3 is correct. I have been making my changes on complete overhauls, when I have clean passages. I have milled heads about .020 on all my overhauls, and the blocks too to make a good surface for the head gaskets. I have never seen passages on the head less than the drilled passages. On a heavily milled head, it could be a problem. Modern oil should solve all sorts of problems. My change is to force more oil all the way to the left end of the shaft. The oil comes up through the second rocker stand from your right in the picture, and exits from the stand on your right. If you look in the hole in the second stand, there is a restricter inside the hole. I made a change to the cam on this one, and flooded the rockers. It took some tuning to get the flow right. I have more pictures to show the wear after ten years of use.
