David,
It's been many years since I've done any foundry work, but if memory serves me, pour temperature is more about surface finish on the casting than shrinkage. I believe a hot pour tends to make the surface of the casting more porous than a pour at the proper temp. Do you use a shrink rule when you make the patterns?
