	I believe the engine should be running to do this! By tightening
down until there is no play(i.e., no valve chatter) and then an additional
turn you place the lifter's inner part about 1/2 way down its bore for
optimal operation. (What you did was tighten down so far that the valves
were probably never closing.)
	Of course the lifters could actually be shot(siezed or excessive
leakdown) and adjustment won't solve the problem. Also, the stuff sold
in cans claiming to quiet noisy lifters probably won't help either.
