We have many .660-.710" or so net lift setups running on the street, road racing multiple seasons, etc. It isn't cheap, & the head needs to be built around it, but it isn't anything new and is more than doable. Spring life can be adjusted somewhat & lash adjustments are typically required every 3-5k miles, though it depends on the individual setup.
Mike's setup is a good example. Relatively mild high .6XX" lift cam, quality parts, highly competent guy, etc.
Most guys are better off spending $ on better heads & staying HR or small/mild SR in our experience.
