Just exactly how are you adjusting the hydraulic lifters???? If your using the truck service manual that's incorrect, you need to use the passenger car service manual. I assume you know that you need to take the adjustment somewhere around a turn past the zero clearance point with a hydraulic lifter with the engine running.
Or, if all else fails, you can, Just read the procedure in the 1949-54 Passenger Car Shop Manual, which is, with engine off, lifter on base circle or low point of cam, 1 1/2 turns past zero clearance compressing the spring which leaves the plunger at its mid-point.
