69 mach 1- Best long tube headers???
 

So I have been slowly putting my 69 mach1 together got motor in and factory manifolds for now but am wanting to open the exhaust up with some long tube headers and 3" exhaust.has anybody come across headers that are fairly simple to install,and good quality??? Everybody knows how tight those inner fenders are to the motor,not much room...will I have to unbolt the motor?what brand holds up good to the environment? Round about price? Thanks and any advice is appreciated!

Oah yeah motor is a 390.thanks

I guess not that many 390s with headers?

They do offer some and I'm just going to look the options up and see what is offered.390 is the same block as 428 so they should have something good
