AWESOME NEWS, Maybe now you'll have some time to look into the 94 in more detail, the head gasket was a Hail Mary toss with the time we had available "to do something" 50/50 shot.
Common failure point is/was gasket, we saw some indications on the removed gasket that showed high likelyhood that was the cause, now that you have 1up and running;
remove heads again, this time take them to a machine shop to have them pressure tested and flatness checked, drop transaxle remove pan and do a bottom up assesment for cracks, from top down block looked good, also do straight edge check of the block to do a "flatness check" of the block deck where heads mount.
