SCD racing gaskets. They're handcut out of Felpro gasket paper and then soaked with yamabond 5 before being installed. They're nearly nuclear bomb proof and currently being used on every SCD racing built engine, even a dragger!
In all seriousness, the cheap vesrah/vito's/K&S "green paper" gaskets have been known, on occasion, to suck in and create a massive air leak potentially endangering your engine (if your quad is currently being piloted by "brick thumb" awk). Cometic or OEM base gaskets are your best bet. Head gaskets are *as far as I'm aware of* all about the same and ALL intake gaskets stink. The real difference is that base gasket, like freek said.
