New head gasket, cam followers, valve guides & seals, reground valves, skimmed head plus other gaskets/seals on a 16v plus you should do the the cam belt & chain & tensioner as they are off. Easily a Grand plus for a proper job. If tight on cash, could reuse the cam followers if they are OK and reuse the cam belt & tensioner if recent, but I would still replace the chain as the cams are out, but over all it would not save you a lot.
