    Long tube, equal length 4 into ones, or Tri Y headers are a definite plus (don't waste your money on "shorty" headers). As far as mufflers, if you don't need them in your state/county, don't use them. You'll save weight without them. If you do need or want mufflers, Magnaflow & Flowmaster are the two favorites among members here from all the responses Ive seen.
    For heads & manifolds Edelbrock is a good place to start, if you can afford them. The manifolds aren't too expensive but their heads are
