As for what kinda headers do I use on ShaZam I built my own 2" Primary 37" equal lenght 3" collector wheelwell exit headers.
I started with a weld up kit from Stahl headers for the Big Block Chevy and they sent the flange plates for the 351C 4V Heads.Welded 2" stubs onto the flange plates and then started to hand fit the rest of the pieces together.
