Welding Cylinder Heads

[79cheyenne79]

I just changed my cylinder head gaskets and still noticed the white smoke. I thought it was because of all of the cleaning chemicals that I used. It was! But after running my 350 it still gave out white smoke from the exhaust. So there was still a leak. Any way my head is cracked I can see the water leterally seeping out. I was wondering if it is a good idea to weld the crack.

If the head is cast iron it takes a person that "knows" how to weld cast iron for it to work. You can't just start welding on it. The head must first come apart, be cleaned, pre-heated, welded (with proper rod), then let to cool slowly. Then after all that it will need to have a valve job done and be resurfaced.

prolly better/more cost efficient to just get some new heads. just my 50th of a dollar though.

A buddy of mine put his heads in his grill to heat them up and then using the proper rod, stick welded them up. He's run them for ever with no further problems so it can be done.

So........If I was to buy a head should I get both? Or can I get away with buying one? I have a 350 if I didn't mention that.

there are so many different cylinder heads for 350s, if you don't buy one that is the exact same casting, its retarded to just get one.
