Ok, I have an intake plenum thing going and need to weld tubing and plates to the log. Needs to be fairly strong..actually nice and strong because it will have to support a Holley 500 or 350, plus about 3 more pounds of aluminum. With road vibrations and heat..Nickel rod would be the way to go right? I am a welder/fab guy of sorts but cast iron is a whole new realm. Must I heat the area to be welded with a torch and what nickel rod and amp do you suggest? I have a stick box, goes to 175. I don't want to crack this head all up, whats the scoop on welding these heads and what kind of metal/steel/iron is best welded using the nickel? I need it to be able to burn in nice on both surfaces for maximum strength. All help is needed.
I was going to drill and tap for 4- 5/16 studs for each inlet but just in case the log is too thin after milling flat..I may need to weld instead.
