need a set of cylinder heads

[big_blue_chevy2006]

well iv been wondering why my heater doesnt blow out hot air for a while now. well after iv taken it apart and figured it out i went over to my dads friend. he tried to figure it out also and well it wasnt to good. first of all i didnt know that when ur antifreeze turns brown its getting to much air to it. 2nd i never noticed that much air bubbles in my antifreeze. we would add coolant it would bubble up and go way down, iv been adding coolant bc it was leaking but after i replaced the thermostat and water pump(where is was leaking) my engine was still loosing coolant. well as soon as he seen the brownish coolant he knew what the problem was. i have a cracked head. he said its prolly taking in exhaust air and its getting into the coolant. there no coolant leaks on the heads tho so it must be getting in the exhaust and evaporating or something? so what i really posted this for does anyone have a set of 350 heads they would like to sell for sort of cheap? i dont care if they have valves, valve springs, etc. or not i jus need the heads. im not wanting to spend a whole lot of money and im not looking for some high performance heads quite yet just something to make my heater blow out warm air again so i wont freeze any more this winter.

You should check out U-Pull-R-Parts, or other junkyards around your area. Im sure you could find some awesome Vortec heads off of something there and with a little work get it to run great plus adding power. On the 350 with junkyard Vortec heads i've seen a lot of people (in the Camaro forum at least, and the mod swears by em) getting 20hp to the ground with just the reworked heads. You don't NEED Vortec heads, but I heard they are really good for the 350, and for a pair you could pick them up for as cheap as $120, maybe even less if you don't get it with valves, springs, keepers ect.
