Cool swap, looks good so far. Definitely change the head gaskets while its there. Lt1's have 1.52 rockers stock so you won't gain anything there, most do 1.6's. Would be a great time to do a small cam if you have the extra funds, if not no biggy. The 93's have a 700r4 (4l60) with a kickdown cable that goes to the throttle body, they are not the electronically controlled 4l60e.
Hope it makes it out to the Circus meet if you are still around
