Headers, need good fitment??

[RustedMetal]

Donut gasket is toast on my 350 ram style manifolds that are rusted to hell and back. Figured I might as well upgrade to some headers since the stock style 350 will be getting alittle work done over the summer. Maybe a 383 kit.

Truck is lowered too. I was looking at Dougs Y style headers or Sanderson shorties from Jegs. I want a mix of performance and fit first, cost is not a huge factor.

I want 1 5/8 primaries with 2.5 collectors, then they will reduce to the 2in Flowmaster 40's then dump after axles. I will later update to 2.5 all the way back once he motor is built.

Any help or opinions of what you guys run in these old trucks. Thanks
