was the compression test done hot or cold try it both ways. this could
be a low reading gauge but try treating the lifters as if they where non
hydraulic give them .006 ths clearance. run the engine that way for a
few days then redo the compression test I have seen engines that loose
power when they warm up. when the lifters  where backed off the engine
came back to life the rpm went up at idle I have an article on my page
about hydraulic lifters
