Head studs AND blocking off or deleting the EGR cooler will let you push things pretty far. You've got to do something with the cooler too otherwise the added exhaust heat from big power upgrades will most definately kill it. There's 6.0's making 500-600 rwhp with basically stock motors that are studded and EGR's deleted. If you have the heads done, make sure they are milled flat before reassembly. If they are even slightly warped or cracked the gaskets won't hold.
