I've heard the same about the IH V8s but seem to have mine pretty well 
sealed up. Need to install an
extra hanger right near the engine so that the weight of the exhaust 
pipe is not all hanging on those two
little bolts at the ex manifold. I've had to replace the odd donut 
gasket when they broke and I put double
lock nuts on the bolts holding the pipes to manifold. Seems to be ok but 
you have to keep them tight.
On another note, my Olds 403 came without exhaust manifold to head 
gaskets I think. It did develop a
slight leak on one side and I found a gasket to install plus a little JB 
weld on the exhaust manifold surface
where it had a low spot. In hindsight I should have taken it to the 
machine shop and had the surface milled
flat. I can hear a slight leak again on heavy acceleration.
