I don't see any problems running those heads (just check P/V clearance), will bump your compression up a little more. Should put you around 10:1 if you're only .020 down. My Stealths CC'd between 79.8 and 81 CCs.

I think if you run those heads though, of course you CAN run the stock intake, but you'll be giving up free power with that thing. A Performer RPM or other good dual plane in conjunction with those heads will feel quite a bit stronger than what you had.
