Yes, on the big blocks using the thin gaskets on both side of the valley pan works well. I always use both, this way you will not get any intake or exhaust leaks. I use permatex aviation gasket cement on both side of the thin gaskets and haven't had a leak yet. It's messy doing it, but the aviation cement holds up well.
Using just the valley pan, unless both surfaces are machined clean will most likely leak.
Chrysler only used the valley pan and never used gaskets on there exhaust manifolds either, but they had the advantage of having perfect machined surfaces when putting everything together too.
