khenderson i think the only difference in the HO version and the other was that the head was different, which accounted for the extra HP

4Jeepn early 4.0L had around 170ish Hp.. then they came out with the HO version with 190ish HP.. YJ's got like 180 ish.. xj had 190 zj 181 ish. Thus your tj is the same thing or there abouts.
