Look like Vortec heads with upgraded springs and machining for screw-in studs.
This includes about $300 worth or more of installation parts http://www.sdpc2000.com/cart.asp?act...2174&pid=89534 . Looks like they will handle .550" lift (the page detail doesn't say that, but the preceeding page does - best to contact them to get the full story).
