If you're adjusting non-OEM hydraulic lifters on a 235 engine, there are two chances of getting a good adjustment, no matter what method you use- - - - -"Slim and none". Do the bottoms of the pushrod balls have the grooves cut into them to allow a little oil to escape as the engine runs? Pre 68 Dave has a good illustration of how to do that modification on his blog to prevent a hydraulic lifter from getting a noisy air lock. If "Deve" says the sun is going to rise in the East tomorrow, I'd want a second opinion. A running adjustment almost never works well.
