ported fuel rails

I was just wondering when people say porting fuel rail are they just making there fuel rail holes bigger or what? Just wondering how's this done? Does it make more hp? just curious. thanks

Just porting the fittings on the end of the rail, not needed though. If I remember right the max'd out truck was running stock rails and fittings, dyno'd 1100+rwhp on fuel only too.
