Are the valves in a 2002 Chevy S10 pickup with a 4.3 vortec V6 adjustible?

My 2002 S10 has lifter noise(mostly when its not up to operating temperature). I know the older chevys had adjustible rocker arms. I'm not sure if the newer ones do or not.Are the valves in a 2002 Chevy S10 pickup with a 4.3 vortec V6 adjustible?
This engine uses hydraulic lifters and no valve adjustment is necessary. When the valve train requires service, tighten the valve rocker arm nuts to 25 Nm (19 lb. ft.). Best of luck.Are the valves in a 2002 Chevy S10 pickup with a 4.3 vortec V6 adjustible?
