To use the 4 gaskets on the valley pan or not?

I have always made them out of thin paper gasket material glued to valley pan with high tack gasket sealer and then used ultra copper permatex to seal ends and corners on bb intakes.
Kind of a lot of work but never had a vacuum or oil leak ever. I believe felpro makes the thin gaskets but I have never bought any myself. I always keep rolls of different thickness and gasket material on hand for whatever comes along.
I think this is a area where you could get a lot of variation in answers. They probably all will
work fine. Starting with clean oil free intake and valley pan is the most important thing.
