>how much does the actual head gasket run?
depends on the head gasket you want but on average, they are less than 50 bucks, generally around 30.
>any gain from it, you have have a very small performance gain from getting a thinner head gasket, it increases your compression, but to my understanding it isn't quite as safe.
>what about total ring seal, how much different is this?
I got a total ring seal with my engine rebuild. What it is, is a high HP head gasket that is actually part of both the head and the block. There are groves made in both the head and the block to seamlessly accept a headgasket. It is a much better seal, and can handle as much hp as you can throw at it. But it isn't cheap, my shop charged me around 300 for the machine work, then the gasket would have to be around another 100. But you have to actually pull the engine, and take off all the accessories, and wait a few weeks.. so unless your doing a complete engine overhaul w/turbo, it isn't worth it.
