Default Re: 8BA compression issues

Update: I have adjusted all the lifters to the recommended settings. As mentioned before, all the valves have been lapped. After reinstalling the right side head, I repeated the compression test. All 4 cylinders were improved but still low at 65#. Added oil brought this up about 5#. ( this engine has never been started since the complete rebuild)The intake is still off so I verified that the valve lash was correct when the leak down device was functioning. The leak down test indicated that all the leak was from the individual intake valve oriface in the block.. I have no idea which valves were used in the rebuild. Is it possible that the valves aren't entirely seating because the stem is being held up slightly in the guide? The intake and exhaust valves are all identical and are stainless steel. Not sure what to do next. Help.
