Only because your engine has roller lifters (from '86-up, IIRC) is it acceptable to replace the old lifters w/new- like BOBCRMAN said already.
You do need to check the rocker arms for wear- especially on the noisy valves. The noise could be from the lifter, rocker, worn or bent pushrod or even from low oil pressure so check this over carefully before you put new lifters in it- it might not need them and they might not fix the noise.
