Default Dohc zc stock exhaust manifold fabbed into a turbo manifold

I am wondering if i can use a dohc zc exhaust manifold and switch the downpipe around and welding it up to be a top mount? I am putting it on a z6 motor but that shouldn't be a problem because the zc ports are larger than the d series ports though it does bolt up fine. I am just wondering if the cast manifold will hold up to the heat. Also i need to know if anyone has welded up a stock exhaust manifold other than the hf one.

Also once it is welded up i would just get a t3 flange welded to it and a custom downpipe. Thanks and hope to hear some good news

no thats wat i mean haha i have just heard the ebay casts are restrictive and i dont really like the wastegate placement on them as it looks like it would be a good oppurtunity for boost creep?
