if you are looking for some better than stock performance then at minimum you should mildly port and polish the stock heads you have on the exhaust sides. i would not pay the 2 grand required to get aftermarket 429 heads for the minimal improvements you would get in a near stock build .. i did step up and get some edlebrock heads for my 351 but they are much cheaper and well worth the 1000 bucks ..you already have over 300 horses to begin with .. just bump up the cam a bit .. add an intake and headers and good ignition and let her rip .. what kind of car are you looking at ?

Some good advice there. Hoss knows the costs, and how to get it done. Along with Tech's advice on the machining you're gonna be right, IMO.
