Hi guys, I'm contemplating getting long tube headers. Where I live, the only law is that 1991 and newer cars must have cats. I've deleted the smog pump & piping, so I assume that this allows for more header options that will fit. What body & year car headers will fit the LT1 B? At some point in the future I'd like to go turbo and/or LS motor, so not looking for something that'll last forever.
