Installing Hardin alum manifolds on my 454, has a dry joint between manifold and riser. A molded hose goes from the manifold to the water inlet on the risers. The Where do the 2 top hoses from the thermostat housing that used to go to the stock risers go ?. The top riser inlet now has the molded hose on it.
Thanks,
Dale

Can you post some pics?

put a T fitting into them and run them into the bottom of manifold with other hoses. or get a 4 hose thermo housing and eliminate altogether.
