I want to do the porting match for larger TB's while I have the motor out and apart. I don't know what I want to do as far as a TB upgrade yet. Is there any reason I can't just port the mani to say 58 or 60mm and just run stockers with stock gaskets for now? I really don't want to buy another Z1 product....
