No, better yet it might be a better option to carve it out of wood......., you could certainly make it work but would it be time worthy or even reasonable??????, come on, dont give out information which doesnt apply to the problem. How many people on here know how to build pipes, the actual fundamentals and hands on experiance? porting?
You can fix alot of things by monkey wrenching, but is it correct>??????? NO! and it certainly isnt the correct response to a very simple question. I could argu that a guy could make parts and stuff all day long, would it be the right answer,,,certainly not.
There isnt a whole lot of people on here that could have the needed tools,ability or the means to even pay a shop neccessary to build new header pipes, porting so lets not make this out to be something it isnt............ a easy swap!!!
