Well, if you have it down that far, you may as well go all the way and pull the engine, split the casing, and do all 4 cylinders. While it's apart, do the 2nd gear fix if it hasn't already been done. The 83, 84 and early 85 had a 2nd gear issue whereas it will pop out of gear under hard acceleration.
Now if you really want a quick 1st gen, get yourself a set of 1200 VMax heads and cams, they pretty much bolt right on...
