Hi, I made a Huge prep on a 300" Cylinder head. One pore in Exaust to water chamber

Which is the best thing to do?

I use big turbo, Methanol, for drag race


Thanks a lot

 

Someone with Eperience fixing this problem?

 

If you can find someone experienced with welding cast iron it can be repaired.

I found a video on youtube that showed a guy using a spray torch with nickel powder to weld up a 427 Tunnel port head that had a huge hole in one of the bowls from some over aggressive porting.

 

Thanks for your advice.
