Valley Gasket (Inlet manifold)

Anyone got any thoughts on replacing the valley gasket with the modern composite version?

The newer composite gasket gives a better seal between the inlet manifold and the heads, particuarly around the waterways.
My father in law always uses the composite gasket when rebuilding the Rover engine.
Hope this helps

By composite I assume you mean the tin gasket with black finish?

They don't rust as quickly and most owners are too lazy to paint the normal tin ones. Possibly a slight added noise reduction. Otherwise no difference.
