Double head gaskit (DHG) is not recommended by OEM, to compensate for an over surfaced head mechanics use it in Pakistan. If at all u intend to use same head the a better solution is welding (A.K.A maal charhana) and resurfacing.
Coming to your question life of multiple gasket is less as compared to the process explained above. In some case heating up issues rise when thw gaskit is not properly installed.
