To me the most important thing to do is prime the oil system. Remove the distributor and use a long cutoff screwdriver chucked in a drill and spin it clockwise and continue until you have oil dripping from the #1 and #6 rockers.
Also don’t use starting fluid as it will wash the oil from the cylinders. If needed, use gas instead.
I’m sure others will chime in to help you get that beauty started. Good Luck!
