Wait, new body?
S478-80 and spool flange. I would bet you can tow with the spool flange safely. Due to the results of mine in the drag truck with a 82, I would put a s478 in my daily driver in a heart beat with a spool valve and it is a 12v with a stock head. With your higher flowing head the results would be even better.
Ron I found precision makes a .96 T4 housing for my GTX4708 that I plan to run on mine but unfortunately it'll be a while yet before I'll ever be able to test it.
I would think the 78-80mm would work best for what you are after and doubt you'd need a spool flange.
Even if you decide to add one later its a relatively simple part to add
