I am using a set of 062 Vortecs 11-98 dated that were bare castings. Didn't cost much to have them assembled and screw in studs put in. The car runs beautifully with these heads but I can't really get on it too much without any seats.
But to answer your question no I am not running those but look on ebay for bare castings and give them to a machine shop for build-up and you will be more than happy.
Make sure they are I think 1998 and later with the back cut on the exhaust valve.

I just bought a set of "out of the box" heads from the local dealer then had my Machine shop mod them..
Cut down the valve guide boss..
new Comp springs (singles, dampers removed)
