Post new heads

I have a 74 350 2barrel nova. I am putting a new carb, intake manifold, cam, headers, and maybe 2.5 inch duals to replace the 2 inch duals. I read in a sbc book that the heads used in my car-I checked the numbers- are not so good. They are designed for economy and have a lump that restricts exhaust flow and have a tendancy to crack. I might be interested in swapping some heads off of an earlier nova 350 '69 maybe? is this a good idea? are there better options? I dont want to spend much money on this, how much would junkyard heads cost? oh I want the engine to run well on midgrade.
thanks
ps the casting # of the heads is 333882

882 are 74 to 79 smog heads you will have very little luck in finding a good set of head at a junk yard they don't call it junk for nothing. i would suggest you save your money and at least buy some dart 2 heads from summit you can get the pair complet with vavle for under 500 new and you can port them later if you want even more power.

those heads have a thin casting and are very crack prone. if u want factory cast iron heads anything up to 1971 is your best bet unless u have money to burn. also check those casting #'s if u want a specific type chamber as well.

Any head with double humps is good.Good large chamber castings are 993,441,487,487x.These are also better castings than 882s crack wise too. I just did a set of 993s for my car cost me $300 for 3 angle job,guides,springs,seals,resurface and magnaflux.
When looking down the intake ports you can visually see were the others have a larger port,the 882s are crapp heads.I compared side by side 461double humps 993s 882s and 305 4bbl heads.The 882s intake ports were visually no bigger than the 305 heads.
Look on Ebay for heads.I did the junkyard humting game a few months ago.I didn't find a single decent set anywere.Also try your local swap sheet.

Personaly I wouldn't blow my wad on after market heads if its a street car.Double humps(if you can find a set)should handle 400hp and decent large chambers are all you'll need for a mild street car.
If you can tolerate the funky valve covers,don't mind buying the special intake and rockers the Vortec heads flow really good.I think they also require a spring ugrade when changing cams and need the guides cut down for over approx .480 lift.
Good Luck and Happy hunting

Another cheap option would be to put 305 heads on.They have crappy ports and small valves but do increase compression to approx 9.5-9.8:1 depending on gasket thickness.They'll make a nice low-lower mid torque machine.I had 305 1.84 valvers on a stock 350 w/ a mild 214/224@00 cam and it was an impresive cheap motor.
