95 Chevy 3.1L SFI OHV 6cyl, stuck valve lifters after making tick-tag noises

done that, and checked push-rods, found okay! Could someone tell me if the stuck lifters are removeable for replacements, and chances for camshast lobes damaged? the lifters have rollers on their bottom though. No engine's overheat as well. thanks

Tear the engine down and replace the worn parts!! Cam lifters ect! Yes all of it can be replaced.

Thank "wetry" for a quick reply. Some said that the camshaft's lobes could have been worn down as well. But if my engine can still run with some roughness from these possible-worn-out camshaft lobes, it is fine with me; I only plan to use this old car for a short commute. How bad the camshaft's lobes would be so that the engine will not run okay? Anyones have experience? thanks!

The affected cylinder(s) may not fire properly (or at all) dumping unburned fuel into the exhaust trashing your converter , causing it to not run ,or before that , overheat and blow a headgasket rendering it completely useless.Maybe diagnosing and fixing it right once will be more effective , even for short commutes.
