This looks like it was made that way. Why? I am wanting to use this
manifold for automotive use. What can I do? It has a big hole in the top
of that about 1" pipe thread. Can I run a tee from there and 1 going to
water pump and other for heater?

Don't know the 318 manifold fittings, but aren't 318 manifolds still
available at auto boneyards cheap? Might be better to use an
auto manifold than tinker with that marine manifold.
