yes, the indicated overall lift is on the stock 1.6:1 rockers.

if it were ME doing this, i would buy a set of heads on the side and get them ported, polished, and the guides milled down to run the cam properly. this cam is an awesome one for you to stumble upon for your setup and it'd be a waste for you to not use it to its' full potential.

however, if you get ahold of 3800 performance you can buy their 'TEP cam install kit' which would give you everything you need to run it.
